Only when it comes to the actually device itself.
But when it comes to sales, the 1.7mil sold in whatever, not a failure.
Cult following and marketing? Not a failure.
Its like a movie that comes out, shatters all records on opening weekend. Only turns out. It was a horrible movie with horrible reviews, it was just marketed very well and highly anticipated. Maybe their goal was just to make all the money back within the opening weekend. Who knows. It won't go down in history as one of the greatest movies but still goes in the history books for having the largest opening weekend.
