Received mine a couple days ago. So far no issues, just a couple things that I've noticed. The palm rest is a lot bigger than I realized. The buckle on my watch will be an issue scraping it. I looked into a guard but Apple says not to use any guard or skin because it can damage the lcd. The other thing I've noticed is that when the computer is off or sleeping the trackpad doesn't get power and I'm used to just tapping it to wake it, not going to happen now. This isn't really an issue, rather just changing habit.
Is the palm rest somehow bigger than before because I didn't notice my watch hitting it before either but now I totally do. Interesting point about the trackpad.
