But they were dependent on external party to manufacture their designs, which was major PIA even in Nokia times when Maemo-devices were manufactured in far east and you never could be sure if they switched some components to make it cheaper without telling you. Turing has a design, AFAIK there have been prototypes for some time now. In that sense, building manufacturing line for single product (at this point) shouldn't be too difficult task as there is still some knowhow left in Salo area.

Um.... I just stated that back in days that factory could churn out such numbers in a matter of couple of days. In that sense manufacturing 300 000 devices in about seven or eight months is a non issue technically. They are another things that raise my eyebrows on this than sheer manufacturing capability of the line.

Besides, you forgot the word "scam." You are slipping.
