That is a very good point. When I go to a tradeshow, I try like hell to see new and interesting things. I keep my eyes, ears and mind open- Whether it be competitors' marketing, packaging, brewing, grinding, PC interfaces, etc... This machine had an article in the Morning Cup and was presented on the back page of said paper Sat., Sun., and Mon. It was also at the start of Roaster's Alley- if anyone missed it they weren't looking. And I honestly believe they did miss something.
As for being astute- let me just say this. It is one thing to speak the language of innovation, it is quite another to be truly innovative. There are those among this group that will move this industry in ways as yet unforessen, and there are those amongst us that will impede our progress with long held, but incorrect precepts. At times it will be difficult to tell them apart, and some will move from one group to another. As for the espresso machine in question, it was made as a tool for the described purposes above, and in that respect it was a success. What I found interesting was that more professionals didn't even take the time to see it. Or discuss it with the artist, and it was truly a work of art.
PS- It had much more press than the party in the parking lot, but many people found that OK (2 kegs in the back of a Penske truck, now that's innovation)
