I happened to be in the biggest film theatre of Slovenia, Kolosej in Ljubljana. While waiting on the long line for the tickets, I was happy to realize that the line proceeded smoothly. By the time was my turn, Windows server showed its best side.
It crashed.
Even thought everything was rebooted, including sale machines in every coffee shops, still the problem remained. After some 20 minutes of waiting at the counter, I got my tickets in old fashion hand written, "free to sit in any place" - tickets.
Go for something stable.
Even the tourist office of Ljubljana uses it Linux.
