If I were interested in using an X based Unix, I'd probably do this and donate a few bucks. I like what Shuttleworth is doing, even as I don't want to use a Linux distro.
If you're interested in an X-based Unix, Ubuntu probably isn't the right thing to look at in the future, since I hear Wayland is supposed to be here Real Soon Now.
I guess I was sort of trying to draw the distinction between OS X and anything else. Would've been faster to just say that. The less X in my life the happier I am.
