For "PC" (laptop and desktop), the market share of Apple worldwide is somewhere between 6% and 10%. Linux is ~ 1 to 2%. The rest is mainly Windows.

Interestingly I could not found Germany on http://gs.statcounter.com/os-market-share/ but here is Switzerland which have one of the highest OS X penetration of the world (the highest?)

I don't have the figures for laptop only, but I don't believe for 1s that OS X is above Windows in any country (of a non-trivial size)

Maybe in certain extremely local areas, you see a highest concentration of mac laptops. Even then, I challenge you to count carefully and come back to us if you still find that mac laptops are more common than laptops running Windows. Of course there are some factors that can bias in favor of mac laptops, depending of where you look at. However, while that can be interesting from a socio-economical POV, keep in mind that Windows market share is, on average, consistently largely superior to OS X, regardless of if running on desktop or laptop computers.

I'm sure some of this has to do with wealth and the ability to pay for intangible, but definitely positive, experience premia. Go into a cafe in New York City or a college library and you'll see a sea of MacBooks. I might say 90% MacBooks (i'm a part-time grad student.) The situation is very different in the workplace, especially in lagging industries. In finance and management consulting, my past careers, I saw 99% PCs.

My casual observation: most commuters don't use a laptop in the train. Those who do, mostly Windows. Apples seem fairly rare, as in, every 20th unit or so.

that is not true. people use clearly more windows laptops in germany
