Sippey believes the iTabletSlateTab will be a laptop with a touchscreen where the screen can fully wrap around. I almost agree, which means it's time for me to stake my claim in the tablet sweepstakes.
The Apple Tablet will actually be the second generation of the MacBook Air. The screen will be 10" (as predicted by many), touchscreen, have very high contrast and will be detachable. That is right friends, the screen will be attached by a magsafe-like connector that keeps the screen attached to the keyboard.
The last time I blogged about the tablet, I thought there'd be some docking station so you can use it as a computer at home. Instead, it will just be half of the computer. I could imagine some kind of stand for watching on the plane or just for around the house, as well.
As for price-point, I think it will indeed be $800-1000. I think they'll add editorial content to the iTunes store using web technology similar to the iTunes LP format (as John Siracusa has predicted). I think it will be based on OS X and not another new operating system, but it will likely require a new 10.6.x version to operate properly. I also think it will be awesome.
