This probably has something to do with the fact that Chromebooks are something like 20% of the new laptop marketshare, Apple commands something like 25 or 30% leaving Windows with 50-60%, whereas Microsoft used to own 90% wholesale of the market. It's a lot harder to replace your old market share with new when you have half of the market presence you did six years ago, and the consumer marketplace is contracting at the same time. Desktop numbers probably look a lot better, but consumers buy laptops 2:1 and enterprise has learned to move from a 3 to a 6 year upgrade cycle.
My next laptop is going to be an Android powered laptop or Chromebook with crouton on it, so I can RDP in to work (windows environment). Nothing I do besides games requires Windows these days, and Steam in Home Streaming will probably solve that as well.
