Paul Hayes tackled this using CSS transitions and their transitionEnd event

His code: https://github.com/fofr/matchMedia.js -- though currently it doesnt support IE6-9, since they dont have transitions, obviously. :)

Usage

#### test 'tv' media type
if (matchMedia('tv').matches) {
// tv media type supported
}

$3

if (matchMedia('only screen and (max-width: 480px)').matches) {
// smartphone/iphone... maybe run some small-screen related dom scripting?
}

#### test landscape orientation
if (matchMedia('all and (orientation:landscape)').matches) {
// probably tablet in widescreen view
}
