Re: missing something
But once you're putting the SBC inside the case, you might as well get a PineBook (this is exactly what they do).
But as a convenient KB/screen for your phone, it could still have it's uses. If I were one to actually use cellular data (rather than syncing through wifi before I leave home) I'd consider it. I had intended a similar idea with the current Barnes & Noble 10" tablet & keyboard, but the KB cover accessory for their tablet is non-functional shit.
