I wish they'd:
1. Provide standardised way to encrypt the whole disk
2. Support Debian by opening up their hardware so one could use stock debian on it (which would also solve problem 1)
you'll pay extra for iMX
BUT it is 100% open. you said you wanted that
Side question: Are already SBCs with the i.MX8 available that have a price that is suitable for individual customers; let's say: < 250 EUR or USD?
