Didn't Microsoft see the elephant in the room? The Metro interface will never work with desktop PCs equipped with (vertical) touchscreens: it's very fatiguing.

Didn't Microsoft see the elephant in the room? The Metro interface will never work with desktop PCs equipped with (vertical) touchscreens: it's very fatiguing. From WikiPedia: "the human arm held in an unsupported horizontal position rapidly becomes fatigued and painful, the so-called 'gorilla arm'" Also quoted from there: "It is often cited as a prima facie example of what not to do in ergonomics. Vertical touchscreens still dominate in applications such as ATMs and data kiosks in which the usage is too brief to be an ergonomic problem."
