Well I seem to remember there was a time beating iOS as a whole was hard to believe, and some still think that's true for tablets, even though Android already has more market share in tablets (each quarter, not yet in total userbase), and it's only a matter of time until it more or less replicates the success in smartphones. This would've happened sooner, if Google's employees weren't so dense to think that they don't have to do anything to push Android tablets, and thinking that devs only need to let their phone apps scale to tablets, which in hindsight I'm sure they also realize what a stupid statement that was at the time.
