I personally enjoy the PS3 better than the 360 for streaming videos and for basically everything else, on the flipside PS doesn't get stuff like Halo or Tenchu, but PS3 has photos, videos, four USB ports, free unlimited internet (browsing and online gaming) and sweet exclusives, The Blu-Ray player is there, no warming up, and because of the USB ports you can put anything on there, movies or music you have on your PC, etc.
PS3's can have errors, sometimes the eye gets broken, it's happened twice in about two years both times were in the beginning stages of launch, and each time they sent us a new PS3, so if you need to send it in I recommend backing up your files onto your PC, also it takes a bit, but it doesn't have the Red-Lines of Death.
The PS3 also has chargers for the Winsaxis, it takes about twenty minuets for about an hour and a half of charge.
Now I'm speaking from a PS3 users experience, I have little Xbox 360 knowledge, I'd recommend searching for someone who's owned an Xbox for more than 2 months.
