It's a yogitype. Sadly it's rubber dome.
You rest your arms on the two rests, with the wrists facing each other. The keys are facing away from you on the back of the uprights. I've only had chance to try it out for a few minutes so far. I'm guessing it'll take a few hours (at least) to get used to it. When you press a key, a corresponding led on the front lights up.
Wow, that's crazy. When I saw the letters on the inside, I thought you somehow had to type with your palms facing outwards! Looks interesting for sure, but I don't think I'd enjoy typing on it.
just playing with the idea. It looks rather nice. But the next thing I'll probably get is something ortholinear. I find that staggered layout works better with lower profile and lighter switches. For example, right now I'm typing on a $12 rubber dome with flat keys, and I find it less tiring than typing on my stock mx clears. I really want a Topre though, don't know what I would make of the layout :/
I use a Truly Ergonomic with MX browns at work. I like the physical layout but find the layout remapping pretty limited (you can only have a single function layer, I like to have extra layers by holding down thumbkeys to do different things - this might not matter to you). Also I've had quite a lot of problems with key chatter and the different firmwares that were supposed to fix it didn't help much. Some days like today it's fine, then others I feel like an absolute idiot for spending so much on a keyboard that is hardly able to perform its one single function.
Have a look at
this blog post about the Truly Ergonomic, I pretty much agree with all of this, and the comments at the bottom about key chatter. There was also a really hilarious post I found about it with the guy typing and not correcting the chatter in his post, I'll try to find it. edit:
found it!. Note that even though he said changing firmware almost fixed it for him, the latest firmware does not fix it completely on my board.
I use an Ergodox at home and I absolutely love it, especially now I have nice keycaps on it (DCS with GMK Carbon Modifers from Massdrop). If given the choice, I would
definitely go with an Ergodox... The Ergodox was just
a bit too weird and difficult to replace for me to take to work.
I could never go back to a staggered keyboard. Ortholinear FTW!
