Earlier this week, Nokia (NOK) announced plans to close its flagship store on London’s Regent Street. These stores were designed to “inspire and educate consumers to the benefits of mobility” and broaden the appeal of the Nokia brand but have apparently done neither, particularly in the North American market, which is among Nokia’s weakest.

“There is no reason for Nokia to have the flagship stores–they cost too much compared to the value they create,” Strand Consult analyst John Strand told Reuters. “Flagship stores are important in fashion industry: Apple is fashion. Nokia is consumer electronics.”

In the end, isn’t the rent the company would have paid on these retail spaces better spent on, you know, developing a worthy rival to Apple’s (AAPL) iPhone?

“On the new online Microsoft Store, we’ve added a bunch of new products, including Windows 7 PCs as well as select 3rd party software and accessories,” Trevin Chow, senior lead program manager for Microsoft Store, said in a blog post announcing the move. “And let’s not forget a ton of gaming products that have been added including a bunch of the top selling Xbox 360 titles.”

Interesting. Not exactly sure what the upside is to selling PCs online when you don’t make them. It’s not like Microsoft (MSFT) will be offering a better experience than, say, Best Buy (BBY), HP (HPQ) or Dell (DELL). And an online outlet doesn’t afford the company the same opportunity to cultivate the “Microsoft Experience” it’s clearly going for in its brick-and-mortar outlets. So why bother?

A unified experience online and off, I suppose. And, if the infrastructure is in place to sell through one channel, why not sell through both? Of course, the downside is that if you don’t execute well, you risk giving customers another lousy experience with which to associate your products.

In a message to clients Tuesday, Piper Jaffray analyst Gene Munster noted that Apple’s online store is currently showing 7 to 10 day lead times for its new lower-priced 13-inch MacBook Pros, and a number of the company’s retail stores are reporting dwindling supplies. “Our records show that Apple has never had a 7-10 day delay on its most popular 13-inch model, with the most recent significant delay being 5-7 days over 2 years ago,” Munster wrote. “We see this as a sign that demand is outpacing the company’s build expectations, and it may take several weeks to reach supply-demand equilibrium. In addition to delays at its online store, Apple retail stores are experiencing shortages in some 13-inch MacBook Pro models. Of the 10 Apple stores we contacted, 7 are short of at least one 13-inch MacBook Pro model.”

That being the case, Munster said he’s increasingly confident Apple (AAPL) will report sales of 2.2 million Macs for the June quarter. Not quite as high as the nearly 2.5 million Macs the company sold during the same period a year ago, but impressive nonetheless. We are still, after all, in a deep recession. Who said Macs are too pricey?

“In 2008, Apple introduced the iPhone 3G at $199, a 50 percent reduction from the previous model, which drove demand up significantly,” Munster said in a research note today. “Most customers will be able to purchase the new iPhone 3G S for $199 (the same price as the previous model). As such, the change in value proposition for the iPhone 3G S is not as meaningful as it was for the iPhone 3G, leading to less of a surge in units at launch. Moreover, the iPhone 3G was available in 21 countries at launch vs. the iPhone 3G S which will sell into 8 countries at launch (then over 70 more throughout the summer). These factors lead us to expect about half as many iPhone 3G S units at launch (500k) as Apple sold in the first weekend of iPhone 3G availability in 2008 (1m).”

So expect a big launch weekend for Apple, just not as big as as the one for the iPhone 3G. That said, 500,000 is a lot of iPhones–roughly five times the 100,000 Pres that Palm (PALM) was reportedly able to move in that device’s first week at market. Interestingly, Apple (AAPL) stopped taking U.S. preorders for the new iPhone 3G S for pickup at its stores tomorrow. The company told Bloomberg that it stopped accepting reservations “to make sure we have the new iPhone in stock at every Apple retail store.”

Such a drastic expansion of Apple-related show floor space will no doubt inspire speculation that the Mac maker plans to put in an appearance at CES. But that seems unlikely given the company’s reasons for bowing out of Macworld. “Apple is reaching more people in more ways than ever before, so like many companies, trade shows have become a very minor part of how Apple reaches its customers,” the company said at the time. “The increasing popularity of Apple’s Retail Stores, which more than 3.5 million people visit every week, and the Apple.com website enable Apple to directly reach more than a hundred million customers around the world in innovative new ways.”

In any event, this is unfortunate news for Macworld and IDG, the publishing company that runs it. Without Steve Jobs or even Apple (AAPL) to help it upstage CES as Macworld has done in some years past, the event has far less to offer attendees and presenters than before. Certainly, no one is going to be decamping from Vegas in the middle of CES this year to hit Macworld. There’s no reason to. And with CES ramping up its efforts to woo Apple accessory manufacturers and retailers, well, things aren’t looking too good for Macworld, are they?

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.

In last week’s Mailbox, you said that Windows XP machines can slow down over time unless you do “a lot of techie maintenance.” What did you mean? I regularly defragment the hard disk, tweak the registry, and clean out temporary files, but my PC is still slow.

All of these things are helpful, though I don’t recommend that nontechie users “tweak” the Windows registry, which contains vital program information that can mistakenly be removed or altered if you don’t know what you’re doing. Another speed-enhancing tactic is to use a program like Startup Cop Pro (snipurl.com/b4v91) to prevent unneeded programs from running at startup, and one like PC Decrapifier (pcdecrapifier.com) to clean out craplets — unwanted pre-installed programs.

However, what I had in mind when I wrote that was something more drastic, something a number of techies I know do annually: a complete replacement of Windows. This involves first backing up all your files, and then performing what’s called a “clean install” of Windows XP that wipes out everything on the PC and starts fresh. You then would copy back all your data files and re-install your programs.

This can make the computer feel like new, but the problem is that it can be tricky and tedious for nontechie users. Depending on the source of the copy of Windows XP you are using for the clean install, you may have to locate and re-install drivers for peripheral hardware and for hardware features of your particular make and model of PC. You may run into licensing and activation issues with your re-installed programs. And you may have to download numerous patches and upgrades for Windows itself and for your programs.

I am considering buying one of the new MacBook Pro 15″ laptops. What do you think of the keyboard on this laptop? Is it easy to type on compared to other laptop keyboards? What do you think of the shiny screen?

Because keyboard and screen preferences vary from person to person, I strongly urge all laptop shoppers to try out models they are considering before buying, even if only for a few minutes at a retail store. Having said that, I find the MacBook Pro keyboard to be very comfortable and easy to use, with good key spacing and feel. I personally prefer matte screens to glossy ones, but own laptops with both types and find the glossy ones acceptable, if not optimal.

I use the Windows Mail program that came with Vista on my computer. You say Windows 7 won’t come with that program. Is there something similar that can be installed?

Microsoft will encourage people to download a similar free program called Windows Live Mail, which is closely tied to its Live online service. Or, you could switch to a competing email program, or rely on Web-based email.

The first: iLife ’09. iPhoto now offers a new feature called Faces, which categorizes photos by faces. The software uses a technology called “face detection” to ID the subjects of photos. It asks you to identify the subjects first and then scans the remainder of your photos; using face recognition, it identifies other photos in which those subjects appear.

Another new iPhoto feature: Places. It does the obvious. Using the GPS geotagging built into newer cameras and “the best cellphone in the world,” iPhoto identifies the location at which photos were taken and categorizes them accordingly. What about photos that don’t include those geotags? Manual entry solves that problem with a little help from Google Maps.

Apple has also added Facebook and Flickr support to iPhoto. Set up your accounts in iPhoto and the software will automatically send your photos to those services and allow your Facebook friends to tag them if you so choose. Beyond these features, iPhoto includes a slick new slideshow and book themes.
