Thanks for the response - honestly, though, aside from the inability to switch WM I'm not sure most of those things constitute the killer features of linux, so much as issues that will bug a relatively small number of people (with the caveat that for most people's purposes, I think homebrew or macports are good enough). You might group them under a larger heading of 'configurability'. Other bugbears are solved by third party applications (different terminal app, command line temperature app, etc). It's fair to say that you might reasonably class such configurability as the defining killer feature of linux - and different people will be more or less willing to trade it off in favour of a lower-hassle experience.
