I have the money to order a new MB Alu. I've read through the Apple forums and on here and have seen a lot of problems involving the trackpad, battery cover, and keys. When I spend $1600, I would like it to be perfect. My question is, do I have a high chance of receiving a perfect MB or is it a high probability that it will have a defect? This is the only thing that's holding me back from ordering one. I'm about 150 miles from the nearest Apple store so any return is going to be a hassle.
