I've been saying it and planning it for months, but I finally bit the bullet yesterday and picked up the PS3. Resistance came with it, and I bought MGS4 as well (surprise surprise).
Overall, with the 2 hours I've played around with it, I think it's definitely pretty cool. I was gonna pick up Iron Man on blu ray as well but decided to rent it instead this weekend.
I'm a little disappointed that it came with NO HD CABLES at all. Had to buy HDMI cables ($50) and a digital fiber optic cable ($25). Plus, since my receiver only has one optical in (currently used by my XBox), I just bought a splitter/adapter so I can use both the PS3 and Xbox on a single optical input. Thankfully that only cost $10.
This is the first PlayStation I have ever purchased and played (excluding the PSP), so the DualShock controller definitely feels very strange. The PS3 80GB comes with the DualShock 3 now, so it's got force feedback, but the controller doesn't seem to fit into my hands as nicely as the Xbox controller does. I'm sure I'll get used to it shortly though. It probably doesn't help that I'm trying to get used to it playing MGS4 as well, since MGS4 has fairly complicated controls. I have yet to use the SIXAXIS functionality.
I think it's kind of a scam with what Sony did though. The PS3 80GB is $399 with SD cables. Why the fuck would you push blu-ray, HD sound, and all the next gen tech, but include a standard composite video and stereo cables. That doesn't make any sense whatsoever. I mean the Xbox360 Pro came with component cables so you could at least immediately get HD going.
The good news? The PS3 has built in wireless, so I was able to connect to my home network without issues, unlike with the Xbox where I had to buy the wireless receiver in order to get online.
I'll be able to finally experience 1080p in movies with the PS3. While I have the HD-DVD addon for the Xbox, I bought my Xbox about two years ago when it came with component cables. And HD video is regulated to a maximum of 1080i if it isn't through the HDMI standard.
