These I found to be 2 major concerns with the new iPod Touch (the rest is wonderful, but I shall not rave about it yet). It seems that the battery is drained rather quickly. Mine can only last 15-20 hours under heavy use (surfing, recording video, playing games, watching youtube, ...). The second issue is that it tends to heat up around the upper back just after a few minutes of watching youtube videos or playing games. A few users have reported the same problem; I wonder if it is due to some kink in the new A4 processor and if it is a normal/tolerable occurrence. Anybody wants to share some thoughts ?
