Stop and think about how you payed twice the price of an xbox and it STILL broke. Then buy an xbox, a live membeship and try playing online WITHOUT PSnetworks lag.
I didn't pay twice the amount of an Xbox, maybe £50 more, my xbox broke after a month, and I've never once lagged on psn. Ever. The only lag i've experienced is those few idiots on games lie COD or MGS or other pvp games who introduce lagswitches to their ethernet cables, something that can be done on all platforms. I enjoy my playstation, I like the lack of cartoony sprites and I love it's exclusives far more than I like xbox's. I will consider getting an xbox again, but never inplace of a ps3.
Besides. I've decided to experiment with the carcass of my PS3. A freind of mine who's a bit of a whiz with electronics has agreed to help me convert it into a playstation laptop, if all goes well I'll do the same with my new slim.
