Android Tablets in last place?

As we know the biggest tablets are the android,ios,and now the surface tablets. Yet the consensus I see among Verge articles and even in other forums are that Android tablets have a lack of apps,performance hiccups, and they don't have that much entertainment functionality.

Now I will definitely be buying a Nexus 4 and that is an area in which I think Android competes on par with IOS and W8. However, when it comes to Android tablets, I don't see any Android tablet appealing to me.

On one hand, the surface tablet has more functionality and office while the Ipad has a large list of tablet optimized apps.

So why have you bought an Android tablet and why should a consumer buy one?
