Love the customization and quickly learning to love the split keyboard. The non-staggered keys are going to take me a long time to get used to. I'm struggling with the bottom row and outer-edge keys the most.
Still happy with it but it's going to be a while before I can use it at work or for anything useful.
Edit*** Already doing a lot better! To be fair, this was an easier sentence...
If you're a programmer rather than a professional typist, you probably can use it at work. It took a couple of weeks for me to adjust, a couple of months to be fluent, but it would have been longer if I didn't use it all day every day.
The biggest hurdles for me personally were
I didn't touch type properly before. I was a fast typist, but my hands roamed freely over the board. I realised that the finger I used to press a key depended on the word where it was used, and that took ages to re-learn.
I bound enter and space to mode shift holds for symbols etc. It works great, but it does mean I sometimes hit enter and send half a slack message instead of typing punctuation.
I'm already doing a lot better, I'm going to take it to work tomorrow. My wpm are in the 60s now, though my accuracy needs some work. I realized I had some bad habits touch typing. I would reach for y with my left hand b with my right.
With Enter being a thumb key I've sent many unfinished typo ridden Discord and Teams messages.
I'm not a programmer, I do a little of everything in the IT world. Most of my typing at work is emails and documentation, but I spend time modifying configs or making/modifying scripts.
