There is a considerable glee at the failure of Windows Phone, which is fair enough if you just hate everything Microsoft on principle. But in reality the Winphones were well liked by anyone who actually used them. They worked well, they talked well to car hands free units and they had the chief, basic "apps".
They didn't have the sort of street cred that makes people rush out to pay too much for an iThingy. Nor did they have the right range for ordinary users, most being either too big, too small, too cheap or too expensive. i.e. There was a big mid-range hole.
But with the right corporate decisions* they would have been a brilliant alternative to the Apple/Google duopoly.
*And they also are a brilliant touchstone to identify the grim level of corporate decision making of Microsoft generally.
