I don't think Nokia is going down. But historically they have made a series of mistakes partially leading to their existing position. Even when they understood the success of the iPhone and Android, they still made that half arsed E7 (EDoF instead of autofocus, Too low res screen, too small battery). They just don't get these simple things. EDoF is a perfect technology for low and mid range, but the lack of macro makes it unsuited for high end and the E-series in particular. Why is this so difficult to understand for Nokia? My point is that seen in a historical perspective there is nothing that suggests their current endeavour with Microsoft is not yet another mistake.
