Well the Nexus 7 out specs the mini in pretty all ways. Display, RAM, processor, graphics, storage (for the price), etc. The software is subjective. When it comes to mobile, Android wins hands down IMO.
The Nexus 7 display is very nice, but there is no contest between the App Store and Play store when it comes to tablet apps. There just isn't. "making progress" != already there.
Also, Apple offers actual support for their hardware. Real, honest-to-goodness, in-person support!
It's not about checklist specs with Apple. Never has been, never will be. It's always amazing how many people simply cannot understand this, even though it's been this way since 1976.
