In Russian it's called Вендекапец and is a bit like second coming.
Maybe it's not happening yet, but the bigger share it has, the faster it'll grow.
And MS and Apple have only themselves to blame.
20 years ago, when the first Linux offensive happened, so to say, with Mandrake and a wave of Linux-native games and proprietary products, and IBM support, people would criticize Linux for having inconsistent chaotic UIs and experience. I was a Windows-only kid, so this is retrospective and people can correct me.
Not sure if anybody remembers, but then you could find most of Windows' important settings in one place, and it looked so polished and patient and relaxing, both 2000 and XP.
Mac OS X was all about toys and shiny colors, but there was also the spirit of it being very polished and consistent and light and fresh.
So - Linux can still be very usable. While both MacOS and Windows even look cheap, I wonder how they managed to achieve that. Even Gnome doesn't look cheap despite desperately trying to imitate MacOS. Not even speaking about ergonomics.
