I have been looking for the same unicorn. I have an Anne Pro2 and while I like the small form factor, not having dedicated arrow keys bothers me. Maybe given enough time I would get used to it, but I'd rather not spend the time learning. Another keyboard that I an trying out is the Drevo Calibur which I have only had for the past couple of days. I am liking it, but really am seeking a bluetooth PCB like the YD68, which I simply cannot find, so I can build my own. I could give up hot swappable switches as I kind of like spending time building my projects, but them I lose the ability to quickly switch to new keys if I decide that I would like to try something different. For now the Drevo will have to fill the void until my unicorn PCB comes along.
