The supposed ski features -- measuring how fast your decents are, skichrono, etc. -- aren't particularly useful for the back-country skier. Racing skiers typically don't need a watch like this - they're on the resort, they need a good stopwatch, held by the person timing them. So I don't see much value in those features.

Out in the backcountry, the barometer, thermometer, compass and slope angle features are great; although one still needs to carry a GPS, and modern ones will have some of those features anyways. One could get the Suunto D9 series instead, but then you miss out on the slope angle measurement, which is a big help in assessing avalanche danger. Also, the light-color on dark background is very helpful for viewing in bright, snowy conditions.
