Oh, in this post, I forgot a third item about the Macbook hardware that drive me bats:
Mac computers started out with one-button mice. I get that: simplicity. Thing is, two-button mice have been supported for some time now, and the OS X user interface makes important use of the second button.
So why on Earth did they design a laptop, in these days of OS X and two-button support, with only one mouse button?
You get the “right click” with a two-finger tap on the track-pad, but it's still not as easy as having two buttons. There's just no excuse for the one-button design.
