I guess it's not black and white. Depending on your settings, and what you're playing, you can get a lot of playtime or very little playtime from your 3DS, With optional Wi-Fi, five brightness settings (in my opinion, five is TOO high. It's like looking into the sun!), and a power save mode, it's not as easy as setting the console and letting it run. I've played my 3DS for six hours one day (admitting that some of that was playing Advance Wars Dual Strike and older games) and the battery indicator still was blue.
Don't know much about the Vita yet. I just feel that, at its best, the 3DS will be better and at its worst, the 3DS will be the worst.
