This is something that scares me. Since linux had a large dominance on ARM, it was common to vendors to make drivers for their devices. By making drivers, I mean get the driver properly mainlined. Of course, there always existed the mostly proprietary and closed board support package but it was to their disadvantage and there was a huge incentive to write drivers.

My fear is that, with windows becoming popular on ARM, this incentive will disappear and linux support on these machine will be weak.

would it be like a situation where they would have to do less work because of existing linux support rather than building new windows support? dunno this looks like another mess then
