When I turn on Media Sharing on PS3 it boots all of my computers off the wireless network, and itself. So PS3 media sharing sucks.
360 takes two seconds to load my shit up and even recognizes my winamp playlists. PS3 makes me make my own playlists (and then limits me to like 100 songs per list

). 360 wins again!
I did recently start youtubing on PS3 and it's pretty awesome though.
