Same with iPads. By far the most common brand of large screen device I see. Outside of office environments I see more iPads than laptops, and even in office environments I'm seeing more iPads today than even just 3 years ago.
iPads are doing exceptionally well, I'm surprised you are unaware. They're replacing laptops for a lot of users, especially those that did not grow up around PCs. It's just that you won't often see them in public.
Apple has a significant presence in Central Europe. Not overwhelming one, American market is obviously a stronger one. It might have something to do with purchasing power parity, which is still not that good behind the former Iron Curtain. But it is a big player here, especially in the richer demographics.
I have never used any Apple products, but I am tempted. People will sing paeans about how their gadgets just work and interact together. I am more of a tinkering-hacking type, so I do not really mind delving deep into my Windows or Linux installation, but Android messes with me sometimes.
There's definitely a huge market of people buying it.
