Pine64 launched an alternative to the popular Raspberry Pi last year, based on an Allwinner A64 ARM-CPU. Now they announced two laptop versions and called them Pinebooks. They will be available starting at $89 and run both Android and Linux.

That sure is a tempting price point, but I wouldn't want to support Allwinner. They've repeatedly violated GPL in the past.
