I think all of the gripes in this article are based around the Metro UI, which was designed to be touch-friendly at its core. Pretty much every single point in this article becomes moot if you actually use the standard Windows desktop.

I think what a lot of people are assuming is that you have to use this new Metro UI exclusively, and the truth is, you don't. If you just treat it as a glorified start menu instead of a replacement to the Windows desktop, suddenly it becomes a lot less scary.
