And the JingPad is currently vaporware. I'm not saying that either works today; I'm betting on which will exist and be usable first.

Considering how many people on the Pine64 forums and messaging groups are claiming to use their pinephones for their main phone, I suspect the Pinetab could be. The number isn't high, but it's higher than I would have guessed before (and after) I bought and started playing with mine.

I'm not saying it's a good experience, but some people have lots of patience and very few (phone-requiring) responsibilities.
