Should I buy a PSP or a DS tommorrow?

[ZaP~]

DS has (personally) more games i like, Nintendo 1st party games, cheaper, more online games, touch screen and its portable [PSP is bigger, has less battery life and its scratches easily]... I almost forget it, it has a lot of 3rd party support coming
PSP has more things to do than just play games, its online doesn't depend on FC, works as remote control for PS3 and better graphics
But you should go and see each other lineups, and see what do you like more, if you like Pokemon i could think that also you could like RPG, so i think the DS is a better option for you
Good luck
