Some of the disdain comes from the ever increasing need for people to carry more and more gizmos when they recreate. We have evolved from no gear, to cord, to beacons with perhaps one or two shovels in the party to everyone having a beacon, shovel and probe, to more sophisticated beacons (that sense heart-rate among other things) to airbags and avalungs and helmets. At some point, people will be carrying so much junk about they won't actually be able to ski any reasonable distance.
It is scary common to encounter people carrying every piece of gear who can't assess a slope, can't navigate without a GPS track to follow, can't move fast because of the gear on their backs and the surfboard sized skis on their feet that they need because they always "ski powder" (yeah right). And, even scarier, they have bought the most recent top of the line avalanche beacon and can't use the thing because it's too complicated!
Personally, after giving it much thought, I decided to continue skiing without a helmet, airbag, avalung or GPS. On some trips, it isn't even necessary for everyone in the party to have a shovel, nice but not necessary.
It's actually refreshing to have another look at the stats on airbags, although it won't affect the choices gear junkies (who seem to confuse having masses of gear with having masses of experience - you know who you are). The Canadian ski experience is very different from the European one as so many of our avalanche incidents are in treed terrain whereas in Europe everything is wide open.
Most people would be better served by improving their skills than carrying another piece of gear, but, that requires way more effort than ponying up to the local MEC store and plunking down some cash.
