One of the comments after the article points to one of my gripes with modern services: increasing pervasiveness of single sign-on. I don't mind signing into Win8 with my live id, in fact it makes migrating settings and such really easy. The problems arise when I want to use an application with a different account than the one that I'm currently signed in as. It just doesn't exist. This bit me hard when I was trying to set up Metro Skype (on a surface rt) to be a standalone auto-webcam, and as far as I could tell there wasn't a way to log into Skype with an account different than the one I used to log into Windows. I had to create a new Windows Live account just for this task. This issue isn't isolated to Win8 (I imagine I would run into similar problems with Chrome OS). It's becoming more common and very, very annoying to deal with.
