I am now in the market for a handheld console and don't really know much about them. The last handheld I owned was the original GameBoy decades ago. I am an adult that likes sports games, puzzle games, adventure games. I am not familliar with RPG's, so Pokemon doesn't really do much to sway my purchase. I am looking at the Nintendo DS, The DSi, and the PSP. Any suggestions?

I've been with a handheld since GBC, currently I have GBA micro, DS and PSP.

PSP gets most of my playtime because it does more than just games. There isn't Zelda on PSP...but there is Kratos. Not to mention demos and DLC from PSN.

PSP is my vote, get a 3000 model.
