That's where I wonder how well received this new interface will be. I wonder if this shell will just become something that most people skip past to get to the familiar Windows desktop. Granted, my experience as a power user (read: I'm a developer writing code and using the terminal--not on Windows but on OS X or Linux) is vastly different from that of a normal consumer, but I still think there is a common ground of using the computer to create rather than purely for consumption.
Still, very interesting concept. I'm definitely looking forward to seeing this released.
