RAM-free SBCs with SODIMM slots

[anchor]

With RAM prices and availability becoming a problem, why not make SBCs without onboard RAM and use a standard laptop SO-DIMM slot instead?

This could have several advantages:

- Much lower base price

- No need for separate 4/8/16/32 GB SKUs

- Users can choose the amount of RAM they need

- RAM could be upgraded later

- Less dependency on onboard RAM availability

Any thoughts?
