Thanks for this article!
I'm not sure how many computers you work at, but I recently changed my set-up so that my two computers and third screen are plugged into a switch selector. This has made it so I can use the same keyboard and mouse on both computers. I also don't have to reach over to my second laptop's keyboard and I can use my vertical mouse all the time. Like you, I also picked up a laptop stand to raise that screen, which has been an amazing improvement.
The keyboard I'm trying right now is the Razer Ornata V4 low-profile with silent keys. But it honestly doesn't feel low-profile. Maybe medium-profile, hahaha. I'd love to try the Microsoft Sculpt but I think I've adapted my typing slightly in response to joint pain, so the split boards are a bit challenging for me to work on. It looks like a very comfortable board though!
