Will the Apple tablet be a full-fledged computer?

Will Apple’s upcoming tablet, slate, pad device be a full-fledged computer? Or, just a handheld device like the iPod touch and iPhone? In other words, will it run Mac OS X (as in the Mac), or iPhone OS (as in the iPhone and iPod touch), or both (as is, ‘Wow! That’d be cool!’)? Dan Ackerman in CNET:

There are two schools of thought on this: either the Apple tablet (or iSlate, or whatever it ends up being called) will be a 10-or-so-inch tablet PC with a full Mac OS X operating system; or it will merely be a larger-screen version of the current iPod Touch, which has a closed, limited phone-like OS.

I’m willing to bet there are more than two schools of thought on this. Why not both?

As much as I want both OS versions on the iTablet, iSlate, iPad device, my guess is that Apple will go with iPhone OS and App Store apps. Why? That’s where the money is.
