Highly recommend PS3. I have mine as the media hub.
I bought the 60GB version from sonystyle. They had $150 credit on first purchase, free shipping, free extra controller and got 8 points per dollar and it works awesome.
Love the Bluray on my 46XBR2. Somehow normal DVDs look very good when played on PS3.
