I just got the newest prototype PSPi Compute boards in, and they are working very, very well. I'm still waiting for the new 2.1A charging chips to arrive, so I can't test that feature yet, but everything else is up and running.
I have some other projects in the works that I'll show off soon, but the PSPi Compute is getting nearly all my focus until it is done.
The PSPi boards are back in stock.
