Post-PC, we need bigger tablets

There does not seem to be much call for larger tablets. Sure, they will be less portable and holdable, but many people already use the iPad on a stand in just one place. And I think they are needed for graphically rich books of all kinds.

Furthermore, it occurs to me that if tablet are seriously going to replace most of the laptops for production uses, then... well, we need a bigger one. A ten-inch touch-screen is of course better to work on than a seven-inch one, but let's get real, for serious work you need something bigger. In fact, if some production uses become *actually* better to do on a tablet than on a mouse/keyboard device, then the biggest desirable size becomes anybody's guess. A 30-inch screen may be a bit hard to swing your hand around on, but probably a 21-inch one wouldn't be too much for, say, video editing.
