There are a lot of variations that you can build yourself and find your actual ultimate keyboard.
I run a low-profile Kyria (one wireless and one wired) with a Miryoku (Halmak) layout, as well as a Charybdis Nano with the same layout and the tenting 'kit'. It however took many keyboards to get to the point where I found the ones I truly liked. (It's a money-pit so don't get into it unless you're okay with spending)
Wonder how it compares to the ultimate hacking keyboard ( Uhk )? I’ve been using it for a few years now and I say the same. They look very similar so curious if you’ve tried it too and the dygma still came out on top?
