Re: Article author lives in a bubble.... Meanwhile reality check...
His point is that cloud game-delivery systems should be able to cope with an automatic system restart. All the alternatives, such as Steam, do. It's not as if he pulled the plug - Windows initiated the restart and the Windows App Store was installing the game. This will happen (a lot).
As for disk space - all installers should check for disk space before running. App stores should be even more user-friendly.
This isn't the early 90s. Expecting meaningful feedback and for installers to just work is a reasonable expectation, especially when using an app store.
