Answer 1

See here: Detecting Touch Hardware in IE 10

From the above page:

In order to test for touch in Internet Explorer 10, which will ship with the first batch of Windows 8 tablets later this year, you can call the window.navigator.msMaxTouchPoints method

if (window.navigator.msMaxTouchPoints) {
// touch device
}
else {
// non-touch device
}
