I've also proposed the Axia IQ system to my boss, here. :)
One of the MAIN reasons I'd like to get this system, is because their board uses PHYSICAL BUTTON SWITCHES! (Any control surface that uses membrane type buttons is automatically OFF the list!) This is a deal breaker/maker for us, because we are live-staffed 24/7/365... so our board's buttons NEVER get a break! ;) They absolutely, positively, HAVE TO BE easily replaced WHEN they wear out.
When I investigated the Axia IQ system, I found that it meets all of the requirements that we have. The only thing I'm lacking, is an opportunity to actually sit at one and test it out. :)
