I have a MacBook Pro. It has the intermittent nails-on-chalkboard screech, which according to AppleCare is caused by a defective inverter. I have an open ticket to send it in for repair.
I also had random shutdowns happening when running battery power, with the battery professing to have 1:50 left. Inspection of my battery revealed it to be bulging and misshapen. It was promptly replaced.
I think this was largely due to the fact that this is a bleeding-edge technology for Apple and they weren't able to get a product of consistent quality out the door in time. It's disappointing for me, but I understand it's not everyone's experience. In hindsight, I should've waited until a few months after the release, and I advise others to do the same.
