I'd like an ambidextrous (or even better, left handed) design as mentioned earlier, where there are buttons on both sides and one could swap keymap layouts. Full size SD card(s) are a must. They store more data at lower prices and greater density. Faster processor, more RAM. Peer-to-peer / ad-hoc WiFi file sharing & IM between tablets; Wi-Fi gaming would be even better. Some kind of gaming capabilities (maybe something derived from the N-Gage failure). Physical screen lock / standby button (something like the sliding button on the top of the iPod). Screen that is easily readable in sunlight.
