I like sony alot because of their quality hardware, and their quality and quantity of games. The ps3 is great at multimedia and has a good game lineup coming up, and i like the size of the harddrive ( if i had 20 gigs i wouldve used it all already). Also, just minor things like wi-fi internet, flash card slots, and the look of teh console make it cool for me.
Alot of us can only afford one console, and since i can only get one i got the ps3 because i think it has it all in games, multimedia, and quality of hardware.
