There seems to be a freezing problem with some of the 13" MBPs, as well as the Core i5/i7 MBPs. I've had mine for about 2 days, and I noticed a hard freeze when I was browsing Google Chrome and listening to iTunes. The iTunes music started looping on a 5-second section and I had to hard restart the computer by hitting the power button. I read some posts about fans and nVidia graphics, so I ended up downloading some nVidia drivers and an application that affects the fan speed. According to nVidia's website, they updated the Mac drivers for the cards that go into some of the MBPs about six days ago, so it MAY be a driver issue. My computer wasn't hot when it happened, so I doubt it's an overheating problem. I haven't had any problems since I restarted, though. Here's hoping that the freezing doesn't start up again; if it does, I'm going to take it to the Apple store to have it looked at.
