The keyboard part doesn't need any certifications. I think they are more about the wireless part (Wifi, Bluetooth, GSM).
Not the whole truth. The chassis and mechanism affect the RF behaviour of the device; the antennas need to be designed against that, it is different when one has an unibody model.
seems to me that it's based (partly) on moto mod development. and it was developed already till prototype phase. so not a big deal to add a PCB and a screen above the moto mod case lol.
I, too would love to know a little more about the team producing this. And should it ever appear, those people had better "shut up and take my money". Seems like we have a number of interesting potential devices (or potentially interesting devices) coming soon.
