Kara covered three Web companies this week, two with very 2.0 names and one about as Web 1.0 as it gets. BoomTown caught up with Mark Pincus of Zynga, the social-gaming juggernaut, right after the company raked in about $180 million from private investors. She got into it with Pincus over those questionable “offer” adverts in the video. Kara was back on familiar territory with a post about AOL (AOL) this week. The rebranded company, which went public a little over a week ago after its spinoff from Time Warner, was still trading pretty much flat as of Friday. And Kara rounded it all out with an attempted peek at Google’s Christmas list. Google (GOOG) has reportedly been drooling over Trulia, the real-estate search site valued in the $150 million range. I guess we mere mortals will just have to wait and see if Trulia’s little green pin marks start showing up on Google’s maps.

Before signing off for the holidays, John managed to bring a week of business bah-humbug to Digital Daily. Apple (AAPL) finally poured the last of the concrete for Psystar’s “special shoes” by winning a permanent injunction against the Mac clone maker. The holidays are always stressful, and the seasonal tension has been heating up over graphics processing units between Intel (INTC) and Nvidia (NVDA). John posted a victory lap in the form of a memo from Nvidia CEO Jen Hsun Huang addressing the recent lawsuit brought by the FTC against Intel. John rounded out the week with some somber news from Palm (PALM), as the smartphone maker released a larger than expected loss for the last quarter of 2009. It might be a lean year under Palm’s tree.

Peter reported that Prime Minister Burlusconi wasn’t the only one to get a black eye this week as Google took a major hit in Italian court over copyright violations on YouTube. Mediaset, a broadcaster owned by Burlusconi, is reportedly seeking at least $730 million in damages. No word yet if Mediaset will be demanding cash or the standard Ferraris and underage models arrangement. Also in big media news, Sony (SNE) and News Corp (NWS) struck a content deal that will now be delivered exclusively to Sony’s Readers. Peter reported that the deal wasn’t big enough to change the balance of power in the content-ebook world but was a clear signal about the future direction of the two companies. Finally, peter reported on Google’s apparent hunger for Yelp and all its delicious restaurant ratings. If the acquisition does happen, analysts expect Google to shell out at least $500 million for the right to add another amorphous noun-verb to its arsenal. We need a new part of speech to describe all these noun-verb companies. I’m coining one. From now on, Google is a “Nerb.”

Maybe it was just the anticipation of all that holiday fudge, but Walt was all over a new generation of glucose meters from Bayer. As the name suggests, the Contour USB offers an important departure from its predecessors in that it connects to your home computer to help you track your blood sugar in a more meaningful way. Walt dutifully pricked his finger several times a day to test the unit and pronounced it a welcome direction for the tool that serves millions of users daily. While software issues and Web connectivity are lagging a little behind, Walt was positive on the device, which seems perfect for the diabetic tech-head. Over at Mossberg’s Mailbox, Walt answered letters about really erasing personal data from a computer before donating an older machine. Readers were also curious about Open Office as an alternative to Microsoft (MSFT) Office for use on a netbook. Walt finished off his bit of pre-Christmas advice by confirming to a reader that Windows 7 could indeed be installed on an Intel-based Mac, just like XP. Katie covered a home stereo gadget that should make the post-Christmas lives of audiophiles a little merrier. The Sonos ZonePlayer S5 can send audio all over your house via your home network. This is the first Sonos product to work right out of the box. The player system gets high marks all around for usability, and is even able to play music form a networked computer’s hard drive, as well as various Internet-based music services.

Weekend Update wished everyone a happy holiday and will be back on Dec. 26 to bring you a wrap-up of all the techie holiday fun you missed while in your nog-coma.

Last year around this time, Sonos introduced its Controller for iPhone, a free application that essentially turns the device into a remote control for any Sonos system. The software performed nearly all of the tasks of the $399 Sonos remote and drastically lowered the price of entry for the otherwise spendy wireless system.

A year later, Sonos is building on the success of that app, launching an all-in-one wireless music system specifically designed for it. The ZonePlayer S5, as the company calls it, encapsulates Sonos’s multi-component system in a single device that can be controlled by an Apple (AAPL) iPhone, iPod touch or computer.

It’s a sort of iPodless iPod speaker dock or, rather, an iPod speaker dock where the iPod can be carried with you. The S5 can stream music from the iTunes library of any computer or networked hard drive. And with five speakers–two tweeters, two three-inch midrange drivers and one 3.5-inch woofer–and a 5 Class-D digital amplifier, the sound is likely to fill a room pretty well. Priced at $399, the S5 is expected at market on Oct. 27.

Consumer electronics devices like these seem an odd shift in direction for a company whose core business has long been peddling switches and routers. But for Cisco it’s another step toward the end-to-end triple play solution for carrier networks and the digital home it’s been yammering on about since acquiring Scientific Atlanta in 2005. Question is, can a company whose name is synonymous with routers and switches expand its brand to include consumer electronics? Certainly, it’s no easy task. Said John MacFarlane, CEO of Sonos, the company that developed what’s now the gold standard in wireless digital stereo systems, “I don’t think that when they hear the name Cisco they think of great products in consumer electronics.”

Now, MacFarlane clearly has a horse in this race, but he speaks the truth. Cisco’s not a brand one expects to see in, say, Magnolia Audio Video. Which begs the question: Is a connected audio component really the best strategy here? “I can’t help but wonder why Cisco is not simply focusing on enabling the connectivity and distribution piece on the network rather than going for the end-point,” Jonathan Greene writes over at Atmasphere. “I’d rather have something neutral that provides access to content (and not just music, btw) where I want it–whether that’s in my house or pushed out to my mobile device. The limited info on the upcoming Cisco product seems to limit the usefulness to a connected audio component. These typically sit in your stereo rack connected to your home network and stream content through as though it was in your audio player. Sounds a lot like Sonos, AppleTV and quite a few other boxes that have been sold with considerably less success.”

A neat little feature, although why anyone would actively use it is beyond me. Text searches on Amazon Mobile–and Amazon’s iPhone-optimized site–are both easier and far, far faster. Why bother with the cumbersome “snap photo-submit photo-wait for Amazon to identify product in photo and its availability and price”?

What this application is clearly lacking and, frankly, just begging for, is a barcode scanner and real-time price comparison function. That would make it a killer app, indeed. And Snappr has proven barcode scanning on the iPhone is possible. The device just needs an improved camera for it to work….

But every time I wanted to change songs, I had to go to another room and make a few mouse clicks on my computer. Ever since then, I’ve been waiting for someone to come up with a good, affordable remote control that lets me change tunes no matter where I am in the house.

Apple’s Remote program

It turns out, I already owned that device. It’s an iPod touch. A new program released by Apple (AAPL) in July was all it took to convert my MP3 player into a sophisticated remote control for my digital-music collection. That program, called simply Remote, runs on the iPhone as well as on the iPod touch, a version of the Apple MP3 player that has an iPhone-like touch-sensing screen and Internet-access capabilities using Wi-Fi wireless technology. Remote is available free of charge on the online App Store that Apple has used since July to distribute software for those devices.

In essence, Remote is a remote control for all music stored on a Mac or Windows PC that’s loaded into iTunes, Apple’s music jukebox software. It allows you to jump between playlists, browse artists and pump up the volume. For the program to work, you need to buy into using other Apple entertainment products.

In the simplest setup, Remote lets you control the music from stereo speakers connected directly to a PC. But it’s most useful when you use a PC to deliver audio to additional speakers around a home — say, a pair on the patio and in the living room.

Apple sells a couple of products that receive audio signals from a PC running iTunes. Both work wirelessly over a Wi-Fi home network so you don’t need to put holes into your walls to run computer and speaker wires. I tested Remote using both. One is an Apple TV, a $229 set-top box in my living room that plays digital audio and video through a standard home-theater system. The other is an AirPort Express, a $99 Apple wireless networking device on my patio connected to a pair of powered A5 speakers made by Audioengine, of San Jose, Calif. A third set of speakers was connected to an iMac in the kitchen, where I store all of my digital music. (The least expensive iPod touch costs $299.)

It was a breeze to configure the Apple TV and AirPort Express to show up as remote speakers in iTunes on my computer. Setting up Remote to give me mobile control over this array of speakers was trickier. After installing the program on my iPod touch, I couldn’t get it to work with iTunes on my PC. After 20 minutes of fiddling with the security settings for my Wi-Fi base station, iTunes finally recognized Remote. I was in business.

We all know how confusing the remote controls for TV sets and stereo systems can be. Remote, by contrast, cleanly displays all the music on my PC on the color screen of my iPod touch.

The program let me flip through artists, albums and playlists with simple finger swipes. But I was sorry that Remote doesn’t have a feature in the iPod touch called cover flow that lets users browse their music libraries by flipping through album-cover art. Apple says it may offer the feature in the future.

The software also let me easily turn on and off the music from my speakers in my kitchen, living room and patio. I could have all the speakers on at once — good for a party. The sound was terrific. The crisp-sounding $349 Audioengine speakers don’t require a stereo receiver.

Because Remote uses Wi-Fi to communicate with iTunes, I could control music anywhere around my house and backyard, which are small enough to be fully covered with a signal from my Wi-Fi base station. That’s a big plus over conventional remote controls that use infrared, a technology that doesn’t work through walls.

One drawback: The battery in my iPod touch drained overnight when I configured the device to stay connected to iTunes, a feature that increases software responsiveness. Changing the setting let me go days without recharging my iPod touch, but it meant I had to wait a couple of seconds for Remote to connect to iTunes when I started up the software — an acceptable trade-off.

Another multiroom audio product with a good remote control is the ZonePlayer from Sonos, an equipment maker based in Santa Barbara, Calif. That system has some advantages over Apple’s offerings, including the ability to access tunes from online music services, such as Pandora and Rhapsody, and separate volume controls for each set of speakers.

The Sonos system starts at $999 for a remote control and wireless receivers, without speakers, that can deliver music to two rooms.

For people who already own an iPod touch or iPhone, Remote is a good reason to buy an AirPort Express, and fill your home with music.

Here are a few questions about computers I’ve received recently from people like you, and my answers. I have edited and restated the questions a bit, for readability. This week my mailbox contained questions securing a wireless network, adapters that play the music stored on a PC through a stereo and voice-recognition software.

Last week you advised readers that, in order to stop people from piggybacking on a wireless network using a Linksys router, they should simply set up a password and keep it private. But don’t they need to enable an “encryption key?”

Yes. Most nontechnical folks would consider an encryption key as a kind of password, and that’s the word I used because I always try to write my columns in plain, conversational English. In this case, however, my use of the term may have caused confusion, because there are, in effect, two kinds of passwords on Linksys routers and most other brands of routers. One just prevents strangers from changing the router’s settings. The other — the one to which I was referring — is required to actually access the wireless network. That’s the one that’s technically called a “key.”

To enable the encryption key, use the router’s setup software to turn on security. On newer models, the strongest security system is called WPA, and on older models, it’s called WEP. Once it’s enabled, only people who know the key can get onto your network. There are further steps you can take, like hiding your network’s name (called an SSID) from others, or even restricting access to the network to specific computers with specific identification codes (called MAC addresses, a term that has nothing to do with Apple’s brand of computers.)

For more details, go to Linksys.com, select “Learning Center” at the top of the page, and click on “Network Security” from the menu that appears. And then click on the link called “How to Secure Your Network.”

Is there a stereo that I can buy that can wirelessly connect to my computer and play the same music I play with Apple’s iTunes on that computer?

Yes. If you literally mean a stereo, rather than an adapter for a stereo, the best I know of is called Sonos ZonePlayer 100. It involves a module you connect to your computer that links wirelessly to stereo units with built-in amps in remote rooms of your house. It has a beautiful remote control with a color screen and many other great features.

But it’s expensive — about $1,200 for the starter package, without speakers — and can’t play copy-protected music you buy from iTunes, only music you import from your CDs or other unprotected files. Information is at sonos.com. For much less money, you can also buy adapters that can play the music on a PC, or an iPod, through an existing stereo.

I have been keeping a journal or diary. It is hand written but I would like to make the journal more readable by others. Is there voice-recognition software that you would recommend, so I can dictate the entries?

It has been years since I reviewed voice-recognition software, but Dragon Naturally Speaking, a Windows program, works well. For more information, see nuance.com. And Microsoft’s new Vista operating system has a decent built-in voice recognition system. If you are using a Macintosh, one widely known speech-recognition program is called iListen, but I haven’t tested it. Information is at macspeech.com.

But there’s a substantial minority of folks who have neither the time, knowledge, nor inclination to do all this downloading and ripping. They don’t want to fool around with any PC software just to hear music. They could just sign up for a subscription service like Rhapsody, which will stream songs to you without requiring any downloading or ripping. But that also has meant using a PC.

The Sonos controller, accessing the Rhapsody music service

Until now. Starting today, there’s a way to get access to Rhapsody’s 2.5 million digital tunes, in any room in your house, straight from the Internet — without even turning on your computer.

This new system is a time/money tradeoff. It saves you time (and what some folks consider a big hassle) in exchange for money: $999 for the basic hardware, plus $10 a month for the music service.

If you’re still reading after digesting those prices, let me add that I’ve been testing this system, which pairs up Rhapsody with the elegant Sonos whole-house music system, and it works very well. It is simple, fast and rewarding.

Both Sonos and Rhapsody were originally designed to work with PCs. Sonos is the most polished consumer hardware system on the market for taking the music that resides on a computer and streaming it to multiple other rooms of your home. It consists of a series of small music-playback boxes that connect to each other over their own wireless network. It normally relies on software you install on the computer. The system is controlled by a gorgeous hand-held remote with an iPod-like wheel and a large, bright color screen that show menus and song information.

Rhapsody, too, is typically dependent on a PC. Users pay a monthly fee to either “stream” music from its collection, or to download it for use on the computer or on a portable device. This is all done using Rhapsody’s software, or a Web browser.

But, with the new Sonos/Rhapsody system, no PC is necessary. You just connect the Sonos hardware to your Internet service, and to either powered speakers or an audio system. Then, simply click on the Rhapsody choice in the menu on the Sonos controller and you can listen to any of Rhapsody’s 2.5 million tracks.

Out of the box, the new Sonos system gives you a 30-day free trial to Rhapsody, without even requiring that you enter a credit card. After that, you must pay $10 a month.

There are other media-streaming devices that can bring Rhapsody to parts of a home far from the computer, and most cost less than Sonos. But all of them, even an earlier implementation using Sonos, require a PC.

Setup of Sonos with Rhapsody was simple. For your $999, you get two small Sonos ZP80 players and one controller. You plug one of the players into your home Internet router so it can fetch the music over the Internet from Rhapsody. The second unit can then be placed in a distant room, with speakers or an audio system, where you wish to hear the music. The two units are linked by their own wireless network, which sets itself up in a few minutes with the press of a couple of buttons.

You can even do this with a single Sonos box connected to the router or to an Ethernet cable running through your walls, if you have one. That would save you some money; a single ZP80 is $349 and the controller is $399, for a total of around $750.

Once you are set up, you just click on “Rhapsody Trial” on the Sonos controller, and you can then select songs via genre, artist and other criteria. Again, there are no files to download. Nothing gets stored on your computer or on the Sonos hardware. The music is just streamed into your home over the Internet.

There are two basic Rhapsody modes. One, called Rhapsody Guide, lets you find and play music, and allows you to “save” the songs or albums to your Rhapsody library. This is a list of songs that the system will fetch from the Rhapsody servers when you want to hear them again. The other, called Rhapsody Radio, consists of over 100 “radio stations” — preprogrammed playlists — based on genres, eras and other criteria. You can also create your own stations.

Although my wife and I aren’t great candidates for this product, because we use iPods and iTunes and have a computer hooked up to our entertainment system, we both got a kick out of the Sonos/Rhapsody package. I found myself scrolling through old rock ‘n’ roll on the treadmill, and she enjoyed a radio station of Broadway show tunes.

There are some drawbacks. Because of complex music-industry policies, a small percentage of songs can’t be streamed, yet they still show up in Rhapsody’s menus, which leads to frustration. And Sonos hasn’t been able to implement a search feature yet, which leaves you doing a lot of scrolling through menus.

But, overall, this is a very good digital-music alternative for people with a roomy budget and a yen for simplicity.
