Should I trade in my 360 for PS3?

Help. I just got a PC and I might get rid of my 360, but I have some questions for the PS3.

1. How is the interface? Can you play music while you play games?

2. How good is the matchmaking in the PSN? Is voice chat supported during a game? Can you check if your friends are online while playing a game? Can you play music while you play online?

everythings good, trade in your 360 for a ps3... i also have a 360 but keeping it for the 360 exclusives, not hateing on the 360 its an amazing system got the red rings once but its okay... but if you do get a ps3 buy the warrenty, im on my 2nd ps3 cause the first one kept freezing on me... so get the ps3 (amazing console) and buy warrenty check out dell.ca they have bundles for the ps3 and there good... i promise you.ephraimromuar
