The smartphone market and the tablet market are two different beasts though. Sure, they both have iOS and Android, but that's where the similarity stops. Android has 3 significant advantages with smartphones that it doesn't have with tablets: more manufacturers making tons of Android phones, more carriers, and the fact that carriers offer Android phones for cheap (or even free) with their contracts. I just don't see the parallel. And (I'm no expert here, so forgive me if I'm wrong) I don't think any of the Android handset makers are pulling in anywhere near the profits that Apple is with the iPhone.
At any rate, when it comes time to drop $500+ on a tablet, why would anyone choose the one with lots of bugs, performance issues, and few apps?
