I charge mostly through the wall (via the cradle), but I don't keep the cradle connected to the computer -- I use the regular USB cord for xfering files. The Cradle sits on my nightstand (where, unlike the computer desk, there is enough space -- and electrical connections -- for it), right next to my Pilot cradle (I do hotsyncs through the wall via bluetooth, but it also charges from the wall). That way I can stick the Reader on the cradle as my final "not quite asleep" action, and it's charged in the morning. 'Course I only charge it every 2~3 weeks or so.
