It's incredible how much Microsoft is resting on their laurels in terms of seeing Windows as insurmountable and so consumers must take whatever Microsoft decide to dish out. I would have been totally resigned to this fact a decade ago, but middle-school+ kids these days don't use Windows - they use Chromebooks. A huge minority of them use iPhones. Familiarity with Windows systems isn't a given anymore in the university courses my friends teach.
When these kids grow up and get to make procurement decisions, are they going to be as tolerant as today's staff of whatever overreach Microsoft is going to try with Windows in the future, or are they - and their peers - going to be much more accepting of non-Windows solutions? I think they'll be much more accepting, especially given how much is done in a browser today anyway.
MS will obviously survive, and Windows will of course remain dominant for the foreseeable future but I can't help but feel that if/when the tipping point for the end of Windows' dominance comes, it will all be seen retrospectively as so preventable, because it is.
