I have been a Kinesis user for 8 years, starting with an Advantage USB, added a classic PS2(with a usb adapter) as a backup and then was a tester for the Advantage 2 which I ended up buying. A company I worked for gave me a choice for keyboards when I joined so I tried a Ergodox EZ with the RGB backlighting. General observations: 1. Overall I prefer the Advantage over the Ergodox. The big reason is the contoured design and the fact that the Ergodox tends to walk around unless you have a solid desk pad underneath it. Also, the Ergodox never felt as comfortable as the Advantage. Yes the Advantage is not as easy to travel with but still.... 2. I like the new design, but there are a few things that would have made the pro perfect. PBT backlit keycaps like they offer on the Ergodox-EZ and RGB backlighting...and maybe a set of f-keys (on the fence with the last one). One other thing... A mix of o-rings and QMX clips made a huge difference with the feel of the keyboard for me. I have been a cherry brown user from the beginning though and different people have different preferences with that. Kinesis is also really good about providing parts and service. I've had them send me replacement switches and have seen them offer up in-expensive replacement boards to repair and keep older models going. I'm going to buy one of these, but given that I already have 4 high quality mechanical keyboards and I have yet to have one die I am starting to feel guilty having all of these laying around. That said there is a side of me that is curious about the Keyboard.io :)
