I'm actually not a blind hater, and have both a PS3 and a high end PC.
I like my PS3. God of War 3 and FFXIII were both a lot of fun, and it makes a great media center. It connects to my PC's PS3 Media Server application, to receive movies and music, and I watch Netflix and Hulu Plus on it quite a bit. Plus, it plays Blu Ray movies, if needed.
What I think the main limitation with it, is the memory. 256MB of video+256MB of system memory, is simply not enough. Load times can get pretty big, and object pop in can be an issue.
Rumors are out there that the new systems might have 2GB of RAM. Which is a LOT better, sure... but, given how cheap RAM is these days, I hope that it's more in lines of 1GB of video RAM + 4GB of system RAM. Anything less, and I'll be disappointed at the missed opportunity to build a gaming machine that actually fixes the last gen of console's primary limitation.
