[$] PinePhone: trying out a Linux-based smartphone

The PinePhone is a Linux-based
smartphone made by PINE64 that runs free
and open-source software (FOSS); it is designed to
use a close-to-mainline Linux kernel. While many
smartphones already use the Linux kernel as part of Android, few run
distributions that are actually similar to those used on desktops and
laptops. The PinePhone is different, however; it provides an experience
that is much closer to normal desktop Linux, though it probably cannot
completely replace a full-featured smartphone—at least yet.
