When I used Mac OS X, everything was very shiny, but also not fully there, functionally. You almost had everything you need, but those few packages that needed to be manually built. And that setting was almost reasonable, but not quite. And there was always something that could be worked around, but never get solved.
So yes, I could run MS Word without resorting to Wine, but I couldn't get any work done without working around many many small issues.
I was glad when that Mac broke down. It was the worst computer I ever had -- even when considering the ThinkPad I had before burst into flames one day -- because the software never worked as I expected it to.
And I'm too old to learn how to reuse my computer. Especially when I can get it running the way I like (as long as I don't use OS X, that is.)
