Really:O? Maybe its cuz I am so used to playing over 5 hours nonstop haha. Also if I go abroad or go somewhere that I can't charge my DS, it would help to last a long time haha. Imagine a plane trip is like 10 hours lol. You would be bored more than half of the time xD. But then again I am sure you dont go abroad that much huh?:P
How much do they cost these days? You have any idea:O?
