I think the wireless turns off itself when the unit is asleep. I think the reviewer was actually reading and had the wireless on during the flight. The wireless is definitely quite a battery hog. My house has marginal coverage so I turn it off unless I need it. I have a Sprint mobile, too, and I find that it's battery gets eaten really fast when the signal isn't good, too. On the Kindle with wireless off, I can read for days. I read well over 1000 screens yesterday and did a little bit of playing with stuff online (checking out Hadrien's links on feedbooks.com) and my battery meter was down by less than 1mm. However, I found that my first session with the Kindle, the battery went down rather quickly. The battery meter said it had a good charge, but it was at half within a few hours of reading. After I did a full charge, though, I haven't had that issue.
