First off, it has a beeter battery life for video as you stated ( you can actually watch an entire movie on one battery charge). Also the screen is much more brilliant and beautiful IMO....it has more features like FM Tuner, recording, etc. and the TV out resolution is better than the iPod's. All that said, is a bit chunkier, but we are talking millimeters here...I would take the Zen anyday over the iPod.
