Another factor in its favor is that it will play for up to 50 hours on one set of batteries, while my flash player will play for 30 hours on one charge.
I think the main reason that battery life has become an issue is that so many devices use batteries that can't be easily replaced by the user. When the battery dies, you only options are to recharge it or attach an external battery pack. This isn't much of an issue as long as you have ready access to a way to recharge your device.[/FONT]

Duracell tried that a few years ago for laptops, if I remember correctly. But manufacturers did not go for it for two reasons:
1.)Using standard batteries takes away from their ability to design devices. As they try to make devices smaller and smaller this becomes ever more important, I can imagine.
2.)Manufacturers are probably making money on replacement or second batteries (even though for many high volume devices 3rd party replacements are readily available).
