Battery life is important for sofa surfers
Having bought a Chinese knockoff (resistive screen, 5 hours battery with wifi off, android 1.6 with no market), I want a tablet with 10+ hours, capacitive screen, instant on and decent speed - I mean, for fsck sake, Apple showed 'em how to make one (that's selling like hotcakes apparently) and, even tho' I dislike the Apple ethos and hate iTunes, I'm kind'a beginning to think about getting an iPad (maybe I could jailbreak it and thus maintain my philosophical anarchist bent).
After all, the best up and coming iPad beater, Samsung tab, offers maybe 7 hours (unproven) on time - (Froyo doesn't have a proper sleep command does it?), it doesn't specify how long bootup takes, and remains suspiciously quiet on price. The screen looks nice but apparently isn't as good as the iPads, and you get no android marketplace.
7 inch vs 10: personal preference, but after experiencing capacitive, it's so hard to go back to resistive, esp. when it doesn't offer anything better (like text recognition). I've been waiting for an iPad beater to turn up, but so far nothing...
