Want to know some more about Apple’s upcoming tablet device? You’re in luck. We’ve received the scoop from our reliable source—who correctly called the iPod nano 5G, iPhone 3GS and Chinese iPhone 3G months ago.

Apple has created at least three separate prototypes of its tablet computer. Let’s call it “iPad.” Version 1 was designed with a 7” screen, which was judged to be too small. The latest version has a 10.7” screen. It runs iPhone OS. There have been reports that it looks like an iPhone. They’re sort of true. It looks like an iPhone 3G, complete with a curved back. It will come in two different variations: one with 3G networking capabilities, and one without 3G networking capabilities. Think of the 3G version as a bigscreen iPhone 3GS, and the non-3G version as a bigscreen iPod touch. Screen resolutions will obviously jump considerably from the iPhone and iPod touch 480×320-pixel displays, enabling easy reading of full-sized book and magazine pages, plus cropped newspaper pages. Expect something like 5-6 times the resolution of an iPod touch or iPhone screen (720p or thereabouts) and 7 times the touchable surface area. It is designed to expand the iPhone and iPod touch media concept to its next potential level: as a slate-like replacement for books and magazines, plus all of the media, gaming, app, and web functionality of the iPhone and iPod touch. It is not meant to compete with netbooks. It’s an iPhone OS media player and light communication device. Apple is currently planning to announce it on or before January 19, 2010, and to use an iPhone-like hype buildup period to start selling it in May or June. It is apparently awaiting a final green light from Steve Jobs; chances of it appearing in the market are believed to be 80% at this point.

Feel free to discuss it all below. Just don’t make the mistake that some of these people made back in May (“what’s the point of putting a camera on the Nano?”). Keep an open mind.
