I saw someone earlier asking why you'd choose Windows 8.x over Windows 7 if you don't have a touchscreen. The simple answer for me, is that it's less resource consumption, and once you actually adjust to how things are done on Windows 8, navigating is easier. Most people just dismiss it because they don't want to get used to something new.
