Supply chain sources tell China’s Economic Daily News that Apple has lined up four new component suppliers for the iPhone 5, which they claim is scheduled for a summer launch. Meanwhile, Taiwanese trade pub DigiTimes is reporting that Apple recently bolstered its printed circuit board (PCB) supply chain in preparation for the next iteration of the iPad. Where the company once used just three PCB suppliers for the device, it’s now using seven. Not a surprise, really, given the 14.8 million iPads Apple sold in 2010. DigiTimes’ sources claim they’re scheduled to begin small-volume shipments next month, before going all out in April. Which jibes nicely with that annual refresh cycle I mentioned earlier and rumors of a spring launch.

As I’ve noted here before, the iPad 2 is expected to be thinner than its predecessor and manufactured with the same unibody approach Apple’s been using for the MacBook. It’s also expected to feature an LCD backlit display, a front-facing camera and Facetime video chat support. Finally, some reports suggest it is powered by one of Qualcomm’s multimode chips and will run on both GSM and CDMA-based networks around the world.

Industry sources are telling the occasionally reliable DigiTimes that Foxconn, Apple’s Chinese manufacturing partner, will begin shipping the next-generation tablet within the next 100 days in preparation for a spring debut that will follow the launch of the original iPad by about a year.

With a 2.4GHz Intel (INTC) Core 2 Duo processor, an Nvidia (NVDA) GeForce 320m graphics chip and 10 hours of battery life, the updated MacBook is similar in spec to the 13-inch MacBook Pro, though with the more budget-friendly price that has made it successful in the education market–$999.

A nice update to a machine that was last tweaked in October 2009, when Apple (AAPL) gave it a new polycarbonate unibody design, LED-backlit display, and multitouch trackpad.

Not much more to point out beyond that, though it’s worth noting that the machine is identical to the one described in a leak to Vietnamese Web site Tinhte earlier this week.

Consider this scenario from Bernstein Research analyst Craig Moffett.

Imagine a portable set top box, but with its own killer screen. When in the home, it would be docked in a cradle connected to iTunes via a wired broadband pipe. Navigation of programming guides and iTunes listings would occur on the iPad, using an intuitive touch interface. Output would go directly to the wide-screen TV on the wall…until you left the house. Then, you’d simply pop the device out of its cradle and take it with you. And in the process, you’d be taking your TV with you as well. A 3G (and eventually 4G) wireless connection would allow you to keep watching live TV in the back of the car or cab. Once you got on the airplane you could choose from a library of your favorite shows saved on your DVR…which also happens to be a half-inch thick ergonomically gorgeous high definition tilt-sensitive screen that fits comfortably in your hands.

A dockable, portable set-top box with LED-backlit widescreen display? Seems a bit of a stretch at this point. And it would be enormously bandwidth-intensive. But it’s not entirely inconceivable, is it?

UPDATE: Mark Sigal recently made a similar observation over at O’Reilly Radar, using MLB’s iPad app as an example:

Similarly, MLB (Major League Baseball) showcased their MLB app, which overlays graphics, information feeds, video clips and live game programming in a way that is simultaneously immersive, interactive and highly entertaining. It is both suggestive of a media-centric killer app for the IPad and a bellwether for the future of TV Anywhere, yet another reason that I believe Apple’s ambitions with respect to Apple TV remain very much alive.

The new iMacs boast LED-backlit 21.5- and 27-inch widescreen displays in an edge-to-edge glass design and all aluminum enclosure. They’re available with Intel (INTC) Core 2 Duo processors starting at 3.06 GHz, and Core i5 and i7 quad-core processors for even better performance. The low-end model is priced at $1,199, the same as the past generation, but its high-end sibling is now $200 cheaper, at $1,999.

The new MacBook features an 13.3-inch LED backlit display, a multitouch trackpad, and a $999 price tag. Though still housed in white polycarbonate plastic, it features an updated unibody design borrowed from the MacBook Pro.

The successor to the Mighty Mouse, Magic Mouse, eliminates mechanical buttons, instead, employing the same multitouch surface found on the iPhone, iPod touch, and Mac notebook trackpads, allowing users to navigate their desktops with simple gesture commands.

Accompanying the Magic Mouse is a a new Apple Remote. It’s got a new design and is, predictably, housed in aluminum.

Finally, Apple (AAPL) also updated the Mac mini. While its design is largely identical to that of its predecessor, it offers far more storage. Starting at $599, the entry-level Mac mini features a faster 2.26 GHz Intel Core 2 Duo processor and 2GB of DDR3 1066 MHz memory, a 160GB hard drive, five USB 2.0 ports, FireWire 800, Nvidia GeForce 9400M integrated graphics and a SuperDrive.

There’s also a new $999 Mac mini that’s specially configured with a Mac OS X Snow Leopard Server. It’s outfitted with two 500GB hard drives for a total of 1TB of server storage.

Quite a refresh and one analysts are already crowing about. In a bulletin released after the announcement, Piper Jaffray’s Gene Munster said Apple’s new machines will undoubtedly improve the company’s prospects for the December quarter.

“We expect the new iMacs, and to a lesser degree the new Mac minis, to help the desktop category rebound in the Dec. quarter,” Munster wrote. “In other words, the headwind that existed in the Sept. quarter due to aging Mac desktops has now turned into a tailwind for Mac units in the Dec. quarter….Bottom Line: Street Mac numbers may also be conservative if positive trends continue coupled with new Macs in the quarter.”

“Field checks confirm that shipments of new MacBooks have begun, with a sharp production ramp planned for September and an introduction planned for early October,” Gardner wrote. “The most distinctive features of the new MacBook appear to be a very thin aluminum casing, an LED-backlit display and an aggressive entry-level price point.”

Gardner expects Apple (AAPL) to introduce its fall notebook line “within weeks.” October 14, perhaps?
