One of the reasons I stick with the Mac is Scrivener 2.  I could quite happily do most of my computing on Ubuntu although I would miss the Mac Hardware.  I couldn't contemplate going to Windows, it has let me down too much over the years even though Windows 7 seems to be OK.  However, Windows is still butt ugly and when you are having to look at it all day, that is a big factor.

Life is just too short to put up with that sort of stuff.
