actually pikachu, my friend bought a 360 today (mines about 2 months old) and the guys at gamestop said all new 360s have the RROD issue fixed (falcon chip) that's not to say a new 360 cant have a hardware failure, it's just not likly anymore. it would be like a PS3 having a hardware failure, maybe a tad more common.
as for getting a 360, one reason, and one reason only: call of duty 4. i would have sex with this game! lol
and you should get halo 3, it's really tons of fun online. story mode not so much (not a big halo fan..)
assasins creed, meh, i wouldnt waste your money. i bought it for PS3 and returned it. it's a rental for sure cause it was fun for about two hours.
