For some of us, though, it was an age of enlightenment, having to work on various unices and then picked up Linux at home. (I started work in the 80s on MS-DOS & Novell environments)
What I have found the last 2 years or so is not that Linux is so awesome, but that Windows is, by itself, simply really bad. Having picked up iOS, MacOS and Android devices recently, they all work pretty well. Windows simply sits by itself in being a remarkably sluggish turd that cannot decide what it wants to look like. Of course, I have not actually had to use Windows 8 yet, but 7 was bad enough of a WTF U/I change (and slow as ever, with klugy programming environment).
RANT ENDS.
