Nice find, and quite interesting 
Agreed !
As much as I hate winders, I still use it for a few things: win95 on my proxy server, w2kpro on my old archiver (not web facing), winvista on the wife's HP lappy.
I totally skipped winxp, win7, win8/8.1 (not interested) but find '10' rather compelling at some level.
Interesting to see winvista and linux usage intersecting in Deutschland. Most Yanks don't have a clue how to keep winvista running.
Then, again, I guess you could say the same about Linux ...
