Sony announces PSP's battery life...

[The Former DMiller]

I agree with OB1. Even though the battery life isn't close to that of the GBA SP, it's still rechargable. I think Game Gear took something like 6 batteries or some unbearable number like that and it only lasted 3 hours or so. However, this still could be a factor since the life will probably be at the low end of that estimate. A lot of people won't put up with a system that only lasts 3 hours regardless of wheter or not it's rechargeable.
