I got my edge on Tuesday and almost shipped it back on Friday. The battery on my unit has a serious problem. No matter how much I charge it, it won't charge pass 48%. I leave it plugged in for over 10 hours and still 48%. I just hope that they do the right thing and exchange the battery. I'm on my Core Duo laptop and it last longer on battery then my edge, of course starting at 48% doesn't help.
