It all depends on pref, and life style... ill explain

Depends on what type of games you like, generally the Xbox has games I like more than the PS3, now the Wii will always have my fun loving games.

Life style, well I have my PC and not much time to sit down on a console anyways so the only reason I'd want one is to take over to a friends house and have some drunken fun, and usually with girls not being very gaming... the Wii will provide those easy fun games like Mario Party, Strikers, SSB etc

so i'd go with Wii, then 360, then PS3. this has nothing to do with price, or how badass the system it is.
