I'm pretty much in the "anything smaller than a laptop needs to be pocket sized" camp - with the pockets in question being able to hold up to say DVD-case sized objects. I'd dearly love something like an iPad in that form factor, but with a clip-on or fold-out keyboard, preferably one that can be used with the screen in portrait and landscape mode. Unfortunately I doubt Apple will ever give us that, so it'll probably end up being Windows 7 or Linux or something.
