Since Cherny requested I "chime in" - and since his recommendation was the tipping point for my PS3 purchase, here goes:
I am very happy with my PS3. I use it all the time. It handles blu-ray discs perfectly - I have a small but growing collection. I have it hooked up to TV with an HDMI cable and it's connected to my receiver with an optical cable. I have bought exactly one PS3 game: The Lego Star Wars Complete Saga. I've used the wireless controller to play it - and I've had hours of fun. I will probably buy one or two more games this year - just for the option of playing games. The PS3 is also connected to my wireless network, and I can stream audio and video from my computer. It's a neat little machine.
The only thing I don't love love love about it is that the upscaling isn't quite as good as my Oppo. When the Oppo blu-ray player
comes out later this year, I'm sure I'll get one, too.
