This is pretty similar to a Keeb.io Viterbi, which is a 70-key ortholinear split keyboard.
I love the Viterbi, it was my first ortholinear keyboard, and my first split keyboard, and I really like both aspects. It completely removed any finger strain I had with previous keyboards. But I wish it had individual RGB backlighting, and I wish it would have hot-swappable keyswitches, because I'm still evaluating different switches.
The ID75 ticks one of those boxes (hot-swappable keyswitches), but it's not a split keyboard, and I'm not sure I could go back to a non-split keyboard...
I think a non-split ortholinear keyboard isn't nearly as ergonomic as a split one, although it's still probably better than a staggered (non-ortholinear) keyboard, at least for your left hand.
With a split keyboard, you can set the sides further apart (about shoulder width), so that you don't "push" your elbows into your body, and you can rotate the sides of the keyboard, so that your wrists are straight (similar to a Microsoft Ergonomic keyboard, for example).
This is pretty great for the price, if only it were a split keyboard (and I wouldn't mind individual RGB backlighting). I honestly wouldn't mind paying even ~300 $ for the "perfect" keyboard (I might even buy a second one for the office). I already have trigger finger on both middle fingers, the keyboard(s) would pay for themselves if they prevent me from needing surgery on my fingers. :P
HumpparitariHmm it's it possible to have individual backlighting with hot swappable switches? I thought you had to solder the led through the switch on to the pcb
