Topic: That was easy
Since one of my C1s had died, I got a Dash of ebay. The larger screen was a driver. It arrived, I did a factory reset, loaded the Chumby software, registered... less than 30 minutes later I had a chumdash.
Then I was about to complain that it kept asking for networks on reboot, but then I noticed this had also already been discussed and answered.
So, err, yeah, "it just worked".
Good stuff, great work!
