The last talks they gave mentioned it is controlled via Bluetooth. So any Bluetooth capable device would be able to connect with it.

Current focus is to use the device as an input device for computers/phones.

This goes against the spirit of the back button. Back button should always take you to the last page you were on. Its always annoying when an app overrides that and instead takes you back to where it thinks you want to go.

Still looking for alternatives for r/mechanicalkeyboards and r/spacex
