Aha! The consideration of "Do I want to be an early adopter?" No good answer to that one. On the one hand, you have the company's reputation to rely on ("They don't build junk, they have a proven track record of not marketing something until they have the bugs out, and they have a no-questions-asked return policy" - one reason MSR gear sells so well.) On the other hand, if it fails in a snowstorm in February, 2 days away from the trailhead, the reputation doesn't matter and the guarantee isn't any good until (if?) you get home.
