there was a guy last year while cat skiing who had a pair of goggles with a HUD built in. It had speed, temperature, elevation, compass, total vertical skied, plus some more information all along the edge of the lens. technology has been around for a few years, but it seams they are working to improve it.
Doubt it will ever catch on with the true skiing crowd out there, but the rich holiday warriors will probably buy into it for sure.
got to use a pair at hood late august they are actually pretty sweet but way to expensive considering it doesnt do anything that cool, they should make some improvements like earphones and stuff and then maybe sell it for $400
