i use my PS3 every day, but i am not even playing games that often. in fact, i still only own 4.
My MacBook has Vuze bittorrent client on it, for which i have some RSS feeds set up with subscriptions for auto-downloading some of my favorite shows.... one of the great things is, this is then instantly shared as a Media Server which the PS3 picks up without any kind of setting up, so i just copy my downloads to the PS3, and watch on my HDTV
Coupled with Blu-Ray, DVD, Picture viewers, music playback, all of which can also come from the networked media server, oh, and along with the option of Linux, it's a genuinely a great bit of kit and has completely replaced my PC.... the 1TB HD i attached tends to help there too
not a bad little xmas present i must say
