Why Would I Buy A 10 Inch Nexus Tablet?

Android has a few hundred tablet apps. That's webOS territory which is a completely dead OS. Why would someone ever buy a 10 inch Android tablet over an iPad or a Win RT machine? I mean I know there are some people who will but unless developers start developing hard for it (which I can't see any reason they would in the foreseeable future) most people won't care about Android tablets over 7 inches.

The N7 I can definitely see as a nice option because it's cheap, small, and the size allows phone apps to not look terrible on it. But a Nexus "10" seems to have no future.
