I'm in the market for a new 7" tablet, and like many have settled on either the Nexus 7 or the iPad mini. A quick review of hardware specs would give the edge to the Nexus 7 with its lower cost, higher resolution screen, etc. and most online reviews confirm my feelings from a hardware standpoint. That said, nearly every head-to-head review gives the iPad the edge for its App ecosystem. Most of the reviews that I have read, however, are pretty light on specifics. Here's my challenge to the forum; gimme the best iOS-only apps that separate the Apple tablets and iOS from the competition. Any category is fine.
