I feel like I can ask this here and get some honest, objective evaluations of both platforms. Any other game website would end in a flame war.
But the last handheld I owned was a red Gameboy Pocket (and it still works, but I lost most of my carts D: ). But I want a handheld. Sony has made it sound like they're giving the Vita some love during the next generation launch, so it might be better in the near future. But what I'm looking for is something with good games, reliable hardware, and good battery life. I'm leaning towards the 3DS because of all that Pokemon and I love me some Pokemon.
