I use ubuntu at work and osx at home. Ubuntu used to be amazing, and I still think it's good open source development platform, but the amount of time I've spent fixing drivers or fighting with unity has meant that it has cost me a lot more than osx.

Then there is the abomination that is unity. They really hit the mark there, making a window manager for netbooks. Cause everyone in their target market uses a netbook, right?

I think they should have stuck with gnome 2, polished it, and targeted programmers as their core users.
