I'm happy to answer any questions around this! We've been working on this since update since we launched the product last year, so we're excited to be able to share it today.
Can existing customers "trade in" their old motherboards for the newer models, with credit applied to make it cheaper?
We don't do trade-ins, but we have released projects to enable re-use of old Mainboards:

I know your roadmap is probably packed to the brim, but if you could help facilitate 3rd party sales that would be useful. My wife stepped on my framework 3 days (!!) after I finally got it back in the beginning, and you couldn't buy parts yet so I bought a whole new framework and cannibalized it for the screen. I've since repaired it but if there was a way to either trade or sell with other people in a similar boat, that would be amazing, particularly where not all parts are available for purchase at each given time.
