The Meta-Battle for SKUs

Apple's identity (account and Touch ID) stategy comes into focus here in this Chart via BusinessInsider.

The meta-battle is now: 

# of exclusive SKUs, Total SKUs, and ease of purchase.  Apple might have the digital content piece (apps, movies etc) but Amazon and Paypal have the physical (and second-hand) universe on lockdown.

TouchID certainly is going to help with ease of purchase, and the rest of the battle is: how can we get consumers to buy ____ with Apple.
