There's an update on Acorns:

This is the first Acorn CLE101 off the PCB production line.

Well theyre coming off the line! So were at least pretty close to schedule. Heatsinks/fans have to arrive, final assembly, burn in, pack, ship. ...
....Long pole is definitely the heatsinks/fans, which have to come off production and ship in from Asia ~
But having the working boards in-hand instills a lot of confidence in timing....
....Target has always been August 31st. Still looks achievable but short delays can always happen.
Ill be sure to let anyone (sic) know if we have reason to believe they will.
