I'm also skeptical of the idea of an iPad with a 7" screen, mainly because typing on such a screen would be far worse than on the current one.

However, such a thing would probably be a lot more pocketable than you'd think. My Kindle 2 (9" diagonal and 3/8" thick overall) fits very nicely into all of my inside coat pockets.

The Kindle 2 also weighs less than half of what the iPad does, which is important; I thought about having a giant pocket sewn in to some of my jackets, but then I realized that I'd need a counterweight on the other side, and I actually got as far as starting the weight-and-balance calculations before concluding that this was getting silly. The counterweight idea would require keeping the jacket buttoned all the time, anyway.

A high-density-screen iPad the size of the Kindle 2 would be worse for movies, photos, and (especially) typing, but I could have it with me nearly everywhere, not just places where I am willing to carry my nerd bag.
