I've purchased and used a number of the GPD products and even contributed to the Arch Linux wiki on the various small caveats of the devices. They generally have good (community) linux support quickly after launch. Build quality is decent as well.
If you're looking to get any GPD device, it's best to wait a few months after launch and they will be on the used market for a decent discount. Lots of early adopters buy these and ditch them because they aren't flawless, but they make fun toys.
