You're right. Newer, better stuff.
My experience was about 10 years old, and these are much, much better.
It might be that the only problem with these things is if once set they can't be turned off. It is very easy when wearing bulky clothing, futzing around for equipment, taking gloves and overmitts off and putting them on, to inadvertently do almost anything. I don't know that that is true, though.
Other than that, you're right. They look great. In the real back-country they could be absolutely superb.
