That was a fun read, but I don't agree with some of it. For the first time in a decade I am considering becoming a Microsoft customer and buy the pro version if the Surface, depending on how reviews are.
I do agree that the desktop computer market will collapse. I have suggested to most of my non-tech friends that the transition to using a good Android tablet or an iPad unless they do video editing of a lot of writing in which case a small laptop works better.
