Your experience with Apple products has been much better than mine!
Except for my iMac and iPhone, and currently my new iPad 2, I have never bought an Apple product that didn't have problems.
My PowerBooks and MBPs all had screen and other problems, and had to be exchanged from the start. Same with older notebooks like my Duo and iBook. My MBP also had the trackpad stop working 3 times and the motherboard replaced twice. My iPod - I don't even want to go there! It had the "tilted screen" problem and I had to end up calling the consumer affairs agency here in Japan to finally get a refund, apology and gift certificate. I never want to touch an iPod again. And I had to get 3 different iPad 1s before I got one without broken pixels.
Apple is usually good about eventually fixing problems. But I always have to prepare myself mentally before buying an Apple product, because in my experience they almost always has some problems which need to be dealt with.
