I totally agree...the ski manufacturer websites, for the most part, are pretty horrible.
I recall 2 seasons ago getting frustrated with the K2 site because they were more concerned with having me feel like i was breaking into Area 51 and discovering some secret goverment lab than actually giving me any of the data on the skis.
All I really want is the dimensions and a brief description of the ski. Include some images of the ski and maybe a comparison of how it stacks up to the other skis in the line.
Volkl's site is pretty decent.
So is Stockli's
And the smaller companies like Line, 4Frnt, Armada, Prior, and the like all have pretty decent sites.
The areas I find most lacking, however, on the bigger company sites, is the bindings.
They rarely give you any technical information about the bindings, opting instead to just show a picture.
Then again, this isn't a problem that only affects ski manufacturers websites. plenty of other commercial corporation websites are just as bad (try checking record company or movie studio sites). I think the problem comes from not having anybody in the company who is truly web savvy and knows what the consumer wants. instead they assume that we all what eye catching candy that features flash videos and neat graphics instead of nuts-n-bolt information. chock it up to the MTV generation!
