get the xbox, it's american so it's good for the econamy (ps3 is sony which is japenese), it's made by microsoft which always makes awsome stuff, the online graphics don't suck (with ps3 they do), and xbox has stuff that you will use and games for the whole family (with the wii it's to childish, with the ps3 its to much adult content).
EDIT: the xbox is rated better than the ps3 and wii by all of the big gamers
