I know 1 specific reason you are so gung ho for a mac tablet perk... LOL
Its blond, a nurse, and seems to become unable to open a particular application on a regular basis...
SSSSSHHHHHHH.

Fucker.
I am intrigued by the idea of tablet. I think if they hop on it, develop some good, Applerific, multi touch apps, they could beat MS surface to the punch, in a smaller form factor. Its not quite the same thing, but, it could be "passed around" instead of "sat around" and would probably satisfy most folks.
In any case, the notion of gestural touch interfaces is on the horizon and here to stay. I really hope that Microsoft pushes the boundaries as well, because the more people/other companies push Apple, the more they have to respond. Have you seen the "chording setups" for the new Macbook? Damn ... 1,2,3 & 4 finger activities, configurable right from the touchpad. I think (well, hope) it's gonna be GREAT.
I agree about the keyboard being dumb. BUT, this could all be solved with accessory open-ness. The fact is, if you had a little roll-up keyboard and mouse that you could just plug into the phone, you would have 1 in every car in the trunk, just sitting there, in case you needed it. No more laptop needed. I would never WORK on it, but i would DO work on it in short minimally necessary bursts, like fixing broken stuff. And a keyboard/mouse would make that MUCH easier.
SPOT ON. If there was a dongle/pigtail I could plug in that gave me a USB keyboard (or USB drive, or USB network connect etc...) that would be awesome. Typing into an SSH with a real keyboard on that little machine acting as a gateway would be superb ... and if I could hook up a network line to it, it'd instantly become my network tester. Hell, for that matter, you could hook up a little VOM dongle to it and have some really interesting calculations done for you...

ooh, I like that one.
Yes you are 100% correct - it's a physical connection so that I could extend the device that would break it out. Interesting, that although 3.0 allows for outboard connection to the box there's not been much activity on that front yet. I wonder what the holdup is, except that even TomTom has not released their GPS for it yet, so clearly it must be a bigger issue than I imagine.
