I have one. I went from a Microsoft Sculpt Ergo keyboard to this one. I loved the Sculpt, but like this better. I'm typing on it now. It feels really nice to type on, the key press feels nice, and I'm happy that I can customize the keyboard layout via simple Arduino programming.
Disclaimer: The keyboard layout is different, and it will take some time to adjust. I think it's worth it, but be forewarned.
Also, hi Phillip! High five!
