keyboard.io keyboards look really uncomfortable for long-term use, what with that hard wood looking enclosure. Ergodox and kinesis both do that weird split keyboard thing. All put other buttons below the thumb which I am not sure about.

Can someone just please make a high-quality MS Natural Ergonomic 4000? Mine is getting worn out.

edit- holy shit it looks like MS reintroduced it! https://www.microsoft.com/en-us/d/microsoft-ergonomic-keyboa...
