While I could understand this approach for big enterprises, to avoid the hassle of managing thousands of employees PCs, I don't understand it for home use.
I mean, people who want a PC at home, want it for the multi-purpose capabilities and power in gaming, not to mention full control over it.
Those who only use the PC for email, browsing the internet and watching videos, are better served with a tablet, they're so powerful nowadays that you don't really need a PC for those simple tasks, students would be better off with chromebooks, they're even cheaper, a few types of jobs, like professional graphics for example, are better done with a MAC, and probably other things I'm forgetting right now.
I fully switched to Linux years ago, but if I were still using Windows, I know for sure I'd be furious if my computer stopped working only because the internet went down or MS servers had some downtime.
I'd love to know what they know that I don't to be so sure this won't blow up in their faces.
