As for my experience - I can say that everything is perfect in this e-reader except power leak. Full charged battery keeps device live for 2-3 days in case of reading 1-2 hours per day. Latest RC3 firmware is installed and automatic power-off is enabled. Can't catch - which process eats battery? Or maybe it's on hardware level (some problem in e-board schematic)?
But anyway - it's very good reader. I like it
