Would it be if they charged for it? Android has massive issues across development, the market, the user experience and poor vendor practices that are routinely ignored by the same people that jump on every mistake Apple makes.
Don't get me wrong, Android has a lot of promise but it's popular because it's on so many phones. That's not exactly a "winner" if it takes dozens of phone to compete against one phone. The same goes for tablets.
The more Android devices you make, the more iOS devices stand out among them.
