Help me decide: PS3 or 3DS?

3DS definitely. And I'm not going to be defending the 3D effect, because at this point it is essentially a gimmick, although not a bad one. The hardware is great for a handheld, the games are fun and cheaper than PS3, plus there are more features and huge titles yet to come. Meanwhile the PS3 is finishing it's last year or so as a major console, and you can find most of the titles on a PC anyways.
At the end of the day, it's fun handheld or occasionally fun home console with more power. Your pick.
