Just curious about your reaction.. I looked at the WinRt ( metro ) interface and I liked it however, in keeping with the Metro ( tiled main menu) Window style, there is no frame to minimize or 'x' to close the application, nor is there a task bar visible without having to hit the Windows key.
In a ( windows ) business setting ( my humble opinion ) I think it is quite rude for an application to take up and 'hog' the screen especially if you have several applications open. Another thing that bothers me is if you click anywhere on the screen the application will close.
As far as using the Metro opening ( tiled ) menu interface ( as is ) .. it is not very pc friendly and would have to be modified to be used in a Business class environment.
In defense of many of our FiveWin friends, I will say that you can still use many aspects of the Metro style for other data entry screens .. like browses and sliders - on off switches .. otherwise using the tiled beginning menu interface does not lend itself to be used as the main menu for a pc application.
