Also, as a mac user for the past year and a half, I still can't figure out when the three coloured dots are useful. Just give me windows-style minimize/maximize/close buttons please...

Every long time Mac user I've asked says they just don't use those buttons. Maximising windows is a mess in mac. Multi monitor support is also rather poor.

Over all, I've had no real problems with OS X (at least after installing my own terminal program and own version of bash and such) and everything worked smoothly, which is great, but I certainly wouldn't hold OS X up as some example of perfect design because there are lots of things windows and Linux do better.
