This week: Imagining a high-end Apple credit card, a potential Square rival and answers to your questions about Touch ID on the Apple Watch, the future of the iPad mini and a new jumbo iMac.

The debut of the new American Express Platinum Card had me thinking a lot about the Apple Card, the Goldman Sachs Group Inc. collaboration that came out nearly two years ago. So far, it doesn’t appear that the card has made much headway: It’s still U.S.-only, the rewards are mediocre, and the revenue impact for Apple Inc. doesn’t seem significant.
