I considered getting the PS3 but, the price tag made it stupid to buy. We decided at the beginning of the year to try the Xbox360 and never looked back. The graphics are awesome, its cheaper (well, not now since sony lowever their price) and alot easier user interface. One thing I loved was in one game, (It was a racing game) you could put in your own CD's and then take those songs, rename them, and use them in the game for your background music. (I dont have the game anymore though)
We watched a DVD on the Xbox last night and playing a DVD on it compared to the Playstations was ALOT easier.
