Okay, I mean some automatic updating software is bad. Adobe's is very annoying, and Windows Update frequently requires rebooting. But some are great -- like Chrome! On a Mac, probably the best thing about the app store is that it consolidates all my software updates (well, not all of them yet) into one place. So the UX is lacking in some places, but it's getting better, and I certainly don't agree with quote's implication that automatic updating doesn't exist on PCs or that software updates don't (in the majority of cases) keep adding value to a PC over time.
