Xbox fanboy says: We need the PS3!
I own an Xbox 360 and I had the original too. And while I find it hard to like the PS3, I still recognise the fact that we all still need a third player in the industry. The gaming industry will be poorer if one faction dominates. This might mean Sony needs to learn from it's mistakes in this generation and take the back seat, much like Nintendo in the last generation.
At the moment though I'm really happy with the 360, it was cheap enough to be within my price range, but not cheap enough that I feel like I'm playing a gamecube in new packaging.
