i think i would go for the ps3 but the controller is terrible, but it is the fastest controller to give arthoritust (soz spell). ps3 you cantribute to caúses if you get online. theres rumours of a secound psp coming out end of next year i know thats a long time but the price will drop dramiticly, and sony will properly stop making games for it.
it really depends what you like. if shooting and racing ps3, if family games like golf, bowling the wii is great and also if you like to move alot then the wii. wii will get boring after awhile but what concele doesn't. you just have get more games.
and if you go out alot then tour properly want a psp to play in the car, but i always feel sick when ever i play hand held in a car, but thats me.
concider xbox 360 thats very good it has a lot of shooting games well known one is halo 3 coming soon, pgr 3, fable 2. family is fusezen (spell) frenzy. if you are concidering a xbox 360 either wait for the xbox 360 elite which is black and had 120 gb and some extra features, or the orignal which will drop price because of the arrival of the elite. if you have one all ready soz for writing this paragraph
