What’s the target use case for this? It seems too small to be useful as a laptop replacement, and isn’t really mobile without cellular radios. About the only purpose I can see is replacing pagers that are still used in medical facilities.
I mean, it is pretty cool to be able to do long range, encrypted, license free communications. Whether it's the be all end all, I don't think so. Reticulum for example seems like a much better thought out protocol. But it's something, and it works right now. HAM is cool and all, but the lack of encryption makes it pretty useless for day to day usage (and to some people's SHTF plans).
It's pretty niche. I'd be interested in it as a device for messaging between folks who are out of mobile range - think farmers, hikers, mountain climbers, forestry workers, fire service, etc.
