You're not going to find anything that's new, freedom-respecting, and has a
modern speed. The EOMA68-A20 card is really the best you can do right now.
For using it as a desktop computer, it will only set you back $120, so it's
perfectly affordable, and it's upgradeable (there are already faster computer
cards in the works, so I guess we'll probably see those some time in the next
couple of years). Upgrades are cheap since you can keep everything else, just
swap out the cards.
> but still not released and not tested.
This isn't quite true. The final product hasn't been manufactured yet, but
the hardware has undergone quite a bit of testing. You can even see videos of
the A20 card running various distros. The delivery time is supposed to be
only in a few months, so that's not much of a wait.
