For those curious, the PineNote is currently $399 + shipping, but out of stock (and has been for some time, not even mentioned on the store home page that includes just about everything else).
As someone who's been following #pinenote for the last ~3 years this isn't true, it's "not dead yet" but Pine64 refuses to ship a second batch until they have a stable community distro to ship pre-flashed. Currently the hardware support itself is sorted, and the desktop integration just needs to be sorted out.
