I'm not arguing that macs are more common than non-macs, only that "In rest of the world (including europe) Macs are seen as luxury environment." is false.
Chromebooks dominate K12 here so it kinda depends on what you mean by "students". Once people start buying their own computers however my impression is that Macs are quite common of not dominating.
Very few uni and high school students have MacBooks in East and Southeast Europe and it’s seen as quite a flex there. They’re also impractical for those in engineering schools due to required software that only works on Windows.
