I've been using Keyboard.io Model 01 boards for a few years now as my daily drivers for typing, ever since they arrived from backing the Kickstarter campaign. For my broad-shouldered build, the split has been good for my shoulders, elbows, wrists and fingers while the ortholinear key arrangement seems to be good for my wrists and fingers as well. Those shipped with Mathias Quiet Click (or optionally Clicky) switches soldered.
I like them enough I've also backed the Model 100 for two boards. These boards are socketed and have a wider variety of switches available. The top enclosure has also switched from maple to walnut.
