While I agree with you that most of these devices are unsuitable for
inflight use, the reason for that lies is the product design, not
the technology. Solid state technology certainly can deliver accurate
signals to fly in IMC if they are designed and tested for that purpose. The
ipad, iphone etc.. were designed for an entirely different purpose, so we
should not blame the technology for their lack of performance in an
airplane.
I remember being told the same thing about GPS back in 1997. The old ADF
was considered far more flight worthy than the GPS.
