You should look at the games all 3 platforms have and see which ones you like best. Personally I have 2 PS3s and I've had one of them since release, never had any problems with either. None of the games on Xbox are appealing to me and the ones that are, are also available on my PS3. I have a PSP as well and was considering getting the PSP GO, but I decided to wait until it drops in price since I can still buy games for my PSP.
If you do decide to go with the PS3, be on the look-out for MAG! Releases in January.
