Why should I buy a ps3?

I'm not interested in blue-ray. I already have an Xbox 360 with xbox live gold and i know psn sucks compared to it. So is there any real reason for me to get one? the only reason i would want it is because of the ps3 exclusives they have and the web browsing which i think Microsoft basically announced they were getting web browsing on the xbox 360 at the E3 press conference. So should i get one?
