As much as I've been looking forward to it, I have to admit I've had the same thought.
No doubt Apple has done tons of usability testing on it, but I'm trying to envision a comfortable use position for a 10" device.
If you multiply the weight of the iPhone by about 3 (which is what 10" seems to come out to) it feels a bit heavy to hold in one hand.
Laying flat on a table would seem to require that your eyes be pretty much right above it, which doesn't sound too ergonomic for the neck.
I can see bluetooth keyboard and some sort of built in stand, but at that point, what's the purpose? You just have a tiny desktop system.
I really am curious to see how they've approached this. Should be interesting.
Totally agree. 7" or so would be a better choice. Then it can be comfortably thumb-typed on just like the iPhone but be big enough to actually do work on and see whole web pages. Personally, I'm still hoping that they are making a new "MacBook" at the same time as the tablet and that the 10" screens are for that project, not the tablet.
I just want a decent portable writing and drawing device. I've been waiting since I saw my first Commodore 64 and it still hasn't happened yet. I wish they'd get their fingers out and do it already.
