ok, i'll bite, nice approach to the Q, its like a Wii, no DVD/Blu-Ray play back, no high graphics, just gameplay...lets do this.
I do have both along with others & my honest opinion is PS3 is better overall, if u think about it really the only edge Xbox has is that they are all modable and u have multiple option on how to mod them.
PS3 just has better games compared to the Xbox 360, I can guarantee that u ask any Xbox 360 player to name u some games they all name the same few games where as the PS3 u would get a lot more answers, even I could name more good games on X360 than an Xbox gamer which says a lot.
Xbox gamers would name these few: Halo, Gears, Forza, Fable (i would go on to name: Alan Wake, Divinity 2, Splinter Cell Conviction to name a few)
PS3 gamers would name: God of War, inFAMOUS, GT5, LBP, Heavy Rain, Uncharted, MGS4, Resistance, MotorStorm to name a few. (& i would go on to name the less common ones like 3D Dot Game Heroes, Valkyria Chronicles, Siren Blood Curse, again, only to name a few).
but to tell the truth, all of Halo, Gears, Fable, L4D (ETC) series are not even exclusive, some of them are on PC n every 1 has a PC or a Mac.
a Xbox gamer will say oh we have a better controller & to tell the truth the PS controller is better as u can use an Xbox controller for a proper fighting game, the D-Pad sucks, and when it comes down to it controllers does not matter in term of which console is better as both consoles can use each others controllers.
I could go on but there is no point, and the fact still remains, it doesn't matter, every1 has their preference right.
