The official reason for the Surface Neo’s delay has not been named. It is assumed that this is due to the consequences of the coronavirus pandemic, as well as the deficiency of components. In addition, the Surface Duo’s disappointing reception could have caused Microsoft to change its mind about releasing the Neo.
Why, then, did the device appear in the film? It was announced in 2019, around the same time filming began. Probably, Microsoft wanted to advertise its product then, but plans could change. Only time will reveal the truth to us.
