Never been to a bike show. At least with other hobby shows I have been to you can find some odd things that solve a problem you may have on a project - I imagine bike shows are teh same way. New functional stuff is great also great, 9 & 10 speed cassettes were real improvements, so were brifters. IMHO wireless 11sp is pure bling. There comes a point were things mature and the improvements are too small to care about. Most things in bikes are that way, but every now and then something really good comes along. I like the idea of a speedplay pedal power meter...
