Funny she (or "he" according to texrat, edit: now I see that it's actually signed by Matthew Stevens) complains about the 2 hours battery time of the thinkpad, since I don't get that much time out of my n800 (maybe the n810 has better power management/a bigger capacity battery).
Oh, and I don't get even an hour out of my thinkpad, so the tablet is definitely better wrt battery life.
