Saving software development costs could be accomplished by moving to Android, without the enormous loss of profit due to paying Microsoft for each copy of Windows Phone 7. No. That doesn't explain the decision. Nokia's new CEO Stephen Elop OWNS STOCK IN MICROSOFT, for whom he is a "former" executive.

Microsoft has already spent half a billion dollars marketing their outdated and poorly implemented phone operating system. Nokia will not benefit from this sell out by their traitorous CEO.
