I think the biggest flaw is that the help system is not a tile on the main screen.
Like the author, I was baffled when I wanted to shut the thing down. I found the thing that shows all the applications on the system, and noticed one of them was a help application. The help application was able to tell me how to shut down. I never would have found it without that help, as it would never even occur to me to look in the settings.
Let's assume for the sake of argument that the new interface is actually good. Regardless, it is sufficiently different from what people are familiar with that people are going to have trouble figuring out things and need help--even basic things like shutting down the computer. Finding help needs to be trivial and obvious.
