Oh and comparing time frames: The Planet computers Astroglide that started in March 2020 (That is seven months before the Pro1X), should have produced 2000 units and "and will be sent to the warehouse in Hong Kong soon.", so I guess they have encountered similar problems as the rest of the industry.
Only making it more impressive that the Slim has been sent out. I wonder if it made a difference in getting what they needed that both FxTex and Planet are British companies, where I believe UniHertz is based in Hong Kong.
