I'm wondering how many of the commentators here have actual read the article.
I've given up using Windows at home, I don't get time lately to play games so I don't miss it. But I'm stuck using it at work and I catch myself wasting time getting upset about Microsoft's behavior with regards to this and have to just remind myself not to worry about it, close the window and move on... I'm there and getting paid to work, not to mess around with stupid crap like this, despite how much it irritates me.
