As for Apple, they do have tiny problems with small things like keyboards and parts inside too, especially when they first push out new products like the unibody Macbook. I personally had to send mine to Apple twice to get the problems fixed. I am not surprised that Apple is ranked the 4th because even they have a high standard (and price) on their products, I have to admit, based on my experience on Mac, the quality is actually dropping as the market share is rising.

Thanks for sharing this with us; it’s nice to see reports like this one.
