Most people who need a desktop OS, want a desktop or notebook that performs faster than a smartphone. Otherwise they can just get an iPad or low end laptop and it won't set you back much more than keyboard + mouse + display. Cloud sync takes care of the rest.
Smartphones are probably pretty close to being powerful enough for 80% of desktop use cases. Having one device that can dock to a "laptop" shell and give me a full screen desktop OS would be amazing.
