PS3 has a web brower for Facebook
PS3 can have Netflix with the use of a media server called Playon.
All my friends have headsets but alot of people don't since it doesnt come with one
More content? PSN has a crapload of exclusive games but Live has more dlc content.
PS3 will get cross-game chat with update 3.00 to be realeased this year.
Also for those who are confused and think that we are talking about in-game chat, no. The official ps3 mic has noise-canceling and high quality mode, 2 things the xbox mic doesn't have.
