There is good music at these shows. And you get access to company engineers to ask questions.
Maybe, but I am not interested in hearing from engineers of mediocre, same-old stuff products. However, it may be fun to hear what the artistic designers and marketing folks of these products have to say, as appearance and hype and salesmanship is where all the "value" is.
As far as music goes, I have plenty of that already, and more all the time.
BTW, if you have never been to one of these, go check it out - it CAN be fun and interesting and something to try -and you can never see too many graybeard orthodontists looking to impress their wealthy friends with the latest fancy-schmancy.
Cheers!
