What a load of crap.
The only way this would be valid is if EVERY desktop app out there would work as a Modern-UI app. If that was the case, then I would have bought an RT.
It is nice to have tablet apps available, but I bought the Pro because I could run desktop apps!! The type of apps you run on the Tablet Side are NOT the same desktop side.
Imagine Photoshop Tablet app that was designed to replace the desktop app.
Imagine Office is Tablet Only.
Imagine all of your Dev and other productivity apps as Tablet Only.
With this first release of Windows with this design, it's NOT going to happen. The UI is too inflexible. When you are in Photoshop, how many other apps do you have running to assist you? When in Office, how many times do you have Word and Excel (of another program) open and the same time to share data?
These people need to do real world use cases and know how people are going to use this vs what they speculate without (most likely) even touching one.
