I'm curious if the fault would pass the test in some legal jurisdiction as being a design flaw and/or manufacturing defect. I guess where I am coming from is should Meridian be replacing these boards when they fail regardless of warranty status.

My own DSW.1 was pretty much never used for years whilst waiting for the firmware upgrade and then failed during flashing less than a week out of warranty so I am understandably unamused that it has since been lying dead in the corner of the room. If I hadn't needed the firmware update or if it had come out sooner I wouldn't be left with a barely used but non-functional product that came at a considerable cost to myself.
