I wouldn't say the Linux support was horrible. It's a bit of a pain to get it installed to begin with, but that seemed an issue with how locked down macs are...

Once I had Ubuntu running, everything worked out of the box. The main issue was terrible trackpad support -- not that it didn't function, but that it didn't feel even close to right. And a few more complex gestures, like tapping with one finger and then dragging with a second, didn't work.
