I see the Wii as more of a child console. I have both 360 and PS3. I have to say as far a multimedia features like game demos, movies, videos etc, the PS3 has nothing.
I like my Xbox 360 a lot more for the features and selection of games as well as UFC fights availiable for download.
The only 3 reasons I decided to buy the PS3 was for the following reasons
-For the controller- I have to admit the Playstation controller set-up is a lot better than 360. And when GTA comes out I want to have it for PS3 because the game feels more true to the PS3 controller set-up than the Xbox.
-For games in Full HD and the Blu Ray Player
- And for 2 other games which are GTA and Killzone 2
If I were you, If you are planning on getting it soon. get an Xbox because they have waaay more games than ps3. PS3 as of now only has 3 good games
