I really want someone to make a mechanical keyboard with a nub mouse. Even with xmonad/amethyst, I still can't stand having to take my hand off the keys to move a cursor. Until someone does do that, I'm going to stick with a Lenovo USB keyboard. But when they do, I'll be the first to buy, especially if it has n-key-rollover for plover stenography.
This one has ended but they said they're going to relaunch it https://www.massdrop.com/buy/tex-yoda?mode=guest_open
