The thing I like most is the split and I have customized the layout to my working style. I really should learn to use layers or try some of the "hacks" https://www.zsa.io/moonlander/printables.
Same for me but even further, after using the Glove80[0] I don't want to go back to non-colstag, non-keywell keyboards.

For a split column-stagger kb I can just order a PCB, MCUs, switches, keycaps and after minor soldering it's ready to go.
With concave boards you need a case of non-trivial design.
And for those reading this thread, if you need a mouse, I've been extremely satisfied with Evoluent's vertical mouse[0]. Unlike most mouse manufacturers, they're very serious about selling what customers actually need - durable hardware, multiple sizes options for every model, just enough extra buttons, and a wired/wireless option for each model. Can't possibly recommend them enough - I went through 3 other vertical mice and absolutely hated all of them (all of them too small, and shockingly Anker's is very low quality; but really I don't trust any with a cheap BT connector).
Ben Vallack has a good video on the voyager[^0] and many other setups and workflows
After using the Ergodox since around 2020 it is hard to see going back to a non-split keyboard. It helps that I also swapped to a trackball at the same time and I find the ergo of having a trackball between a split keyboard to be excellent.
Also, having the backspace key as the "home" key for my left thumb has greatly increased my typing speed....I make a lot of mistakes.
On a traditional keyboard, you can't access the arrow keys with your hands rested on home row. You have to move your hands to reach those keys.
Holding a Fn key brings more of the keyboard's functionality to within easy reach of the hands, at the cost that the keyboard is somewhat more complicated to use.
I've had my Ergodox EZ [2] for ~7 years now. The biggest problem that happened was that some of the switches started malfunctioning - fixing which was a matter of literally 5 minutes.
I don't think I would want to go back to non-split, non-ortholinear keyboards nowadays. 00Key looks cool though, that's for sure! :)
