I think that is a much better argument. It's not that Win 8 is bad, it wasn't really needed for most people. I'd been just as happy if Win 7 was still the latest release.
That's what many have been saying all along though. There is this silly us vs them mentality that seems to erupt between early adopters and other users.
Another way to look at it is that few people WANT Microsoft to fail, we all have a shared enthusiast desire for them to succeed if anything. I would love it if Windows 8 was great for desktop users, a huge success and boosted PC sales. Unfortunately that doesn't seem to be the case so far. Metro was a big gamble, they put a lot into it and didn't take user feed back into account. Maybe people will buy into the unified platform idea but I'm not sure people are so adverse to fragmentation.
