Meh. I started using Linux as a desktop OS in 1997 and used it exclusively from 98-2001 (no dual boot, no Wine, no Windows VMs). With Win2k, I went back to Windows on the desktop, eventually moving to WinXP, then Win7. While I love Linux on the server or small footprint side, I have no need for it on a desktop or laptop. Frankly, since Win2k, Windows works for me and I don't suffer the failures, issues, difficulties, etc that everyone seems to experience. I've found Win7 to be the best desktop OS I've ever tried.
I still give Linux a try on a desktop from time to time to see if things have changed enough to warrant a switch. But so far, I haven't seen anything compelling enough to switch back to Linux.
FWIW, if your Linux experience begins after 2000, you've had it easy. Prior to Redhat 5 in 1999, Linux was a PITA to install on anything that wasn't purpose built to run Linux (total hell to install on a laptop). I built my first dedicated Linux box in 1997, selecting components with known Linux support, and it still took a lot of tinkering to get it all working. Redhat 5 was the first Linux distro to autoconfigure many devices properly at install time. LCD displays, modems, sound cards, etc all worked. That was a quantum leap compared to what came before with Linux.
