>The closed-source nVidia drivers are a pain in the ass to use, though, and nouveau isn't up to snuff. Multi-monitor support is also simply not good enoughl the baseline isn't "usable", it's "as good as OS X", and, for me, I don't find TwinView (is there a different hack for 3+ monitors now?) as don't-have-to-care-about-it as OS X.

Why didn't you just say "I've haven't used it lately" and be done with it.
