Quick update - my Magicforce 68 v2 Bluetooth from Massdrop turned up a few days ago, and it’s excellent!
So, it’s not quite the Unicorn, unfortunately, but it’ll get me through until the Unicorn appears (the MF68BT has no reprogramming capability, no hotswap switches).
If you’re looking for something Unicornesque, buy one of these in the meantime.
Of the four items on my list:
- The form factor is correct.
- The Bluetooth 4 switching between three paired devices is fast and reliable.
- I bought mine with Cherry MX Whites so (whilst not hot-swappable for Heavenly Ocelots or Box Mondegrens) my tactile-switchiness factor is still pretty good.
- The lack of reprogramming capability is a tad vexing, as the CTRL / WIN / ALT keys change function depending on what device you connect to. Not a deal breaker by any means.
The last point is interesting to me, as it makes me think about the ideal behaviour of a programmable BT keyboard that could switch between up to four (BT1-3 + USB) devices of wildly different types. I need to properly map what the keys do on Windows, iOS, and macOS and ponder a bit more on it.
