THIS IS PRETTY COOL: So at the Insta-Daughter’s suggestion, I bought a Mophie Juicepack Air case for my iPhone. It’s pretty cool — the battery life is excellent, and I actually like the way it feels in my hand better than the iPhone alone. (You might feel different if you have small hands). Nice gadget.

UPDATE: A reader notes that some comments at the Amazon link say that they got counterfeits. Jeez.
