Again, if you're just listening to music with no visuals at all then it should last, as I said yesterday, about eight to ten hours just like an iPod would. If you are playing a game that is consistently cycling through and putting the CPU to good use, yeah, battery life is going to be shorter. Maybe about two and a half, three hours. That's why putting the range in there... because it's more difficult because it's got a wide range of applications to really pinpoint to say, "It's eight hours." Because it could be longer, or it could be shorter, and by dramatic margins up or down.
