ErgoDox EZ. I got one at the recommendation of a friend who has battled serious carpal tunnel over the last five years. He said this keyboard changed his outlook and made him a solid 2x faster when developing in vim. Relatively high learning curve when you first get started. You have to get used to a split keyboard and all of the custom modifier keys you have added alongside the bezel. But once you spend some time wi…
I was a fairly good touch-typist before the Ez, but it did take me about 3-5 days of feeling like I was learning to type all over again. Some of that was the thumb clusters, some of that was getting rid of some bad habits. I used to type the "b" key with the wrong hand, which isn't a good option on a split keyboard. I also used to always look at the numbers when I typed them, and I got blank keycaps on the Ez to break myself of the habit. Oh, and I used to always press shift with my right pinky only, and I wanted to break myself of that.
I also switched to i3wm tiling window manager at the same time, so I customized the keymap for that.
Love the Ez. Though, I did go through quite a phase of "Surely the perfect keyswitch is on the other side of this fence... I'd tried Gaetron Brown, Cherry Blue, Cherry Brown, Kailh Box White. At the office, the blues were just too loud, but I loved the feel. The Cherry Browns were fine. The Kailh I currently have in around 1/3 of the switches in my home keyboard, where I'm not as noise constrained, and they feel fine, and they're probably quiet enough for the office. They feel good, but I honestly have a hard time telling which has it and which has the Cherry Brown.
If at all possible, don't go down the "which switch is right for me" rabbit hole...
