Looks like a great full-ergo keyboard for those willing to make the permanent switch and willing to relearn a layout but probably too extreme for most people in its deviation from the standard layout. I use lots of keyboards in various locations and on various devices and even if I only had to have two keyboards I'd want them both to be the same layout.
Given the low-volume of sales for this niche market of non-standard keyboard layout, coupled with the keyswitches and sliding palmrest, I don't think it's unreasonably priced. I'm just confused why there's only standard layouts, and
full-send layouts. Why does nobody want to make something semi-ergo, but fully usable as a 99% standard layout like the old MSNKE with a modern USB or Wireless interface and some proper mechanical keys?
