Thank you for looking into it some more. If the CPU can play most videos fine, then that's still good. Hoping to see more progress.
I'm more interested in thumb/handheld use cases. The Cosmo Communicator is more of a table/lap device or at least an uncomfortable thumbing experience. So if both the Cosmo and Pro1 get decent desktop Linux distro support, then I'd choose the Pro1.
I'm also looking at the DragonBox Pyra with built-in LTE (it also has a mouse pointer). Although, I'm not sure the very old SoC is good enough and I don't really like the gaming design of it.
