The last page of the schematics indicate connectors for QUADSPI, USART, SPI and microSD. No mention is made of any of these connectors on the web site, so I'm sure they're not populated . . . but could be?

The processor supports USB OTG, but the USB ID pin is left floating (pity!) so it can only be used in device mode. I wonder if the pin is brought out to an appropriate TP?

The ease of assembly and disassembly is highlighted, as is the fact that the parts can be 3D printed yourself (no sign yet of the design files). The keys are molded on a sprue carrier prior to silk-screening. I wonder if custom keys can be ordered or done yourself with the raw keys in their carrier?

See Tim's many posts about the Prime for reasons that the software is tightly controlled. But I wonder if the hardware platform might be available separately?

Methinks I'd like to see inside...
