Ergohaven HPD (High Plains Drifter) – a split and curved keyboard. The curved shape is supposed to add extra ergonomics, making it easier to hit the top row keys. There are lots of videos on YouTube about this – just search for "dactyl manuform" reviews.

The thumb keys placement on the Ergohaven HPD is also well thought out – really comfortable!

Compared to my favorite, the Moonlander, the latter wins for me because of the greater number of keys, which I find important and useful for daily work.
