The Metro interface is designed to work on BOTH desktops AND mobile
Is it?
It is designed for touch devices, desktops are an "inconvenient truth".
A friend of mine has a touch Asus desktop.
After playing with touch aspects of the new PC on the first day he never used touch again.
The screen and applications worked better with mouse and keyboard.
Metro apps will be designed for touch, not the mouse and keyboard.
They will be harder to use Metro apps on the desktop than "Classic Windows" applications.
The fact that MS is ignoring this truth is a real concern - what else is MS considering?
