Surface has not done well.

Microsoft has only begun to show a small marginal profit over costs, and were a money-loser for Microsoft for two years. That’s not good. Meanwhile, Apple makes many billions in revenue each and every quarter from iPads.
Well then by that definition Android isn’t winning.
