Today, the man beside me in the coffee shop was working on a PlayBook. I’d never seen one in the wild before, so I looked over his shoulder as he used it. Then he pulled out an iPhone to send an email.

I tried not to smile as I took my drink and went out to the street. It was only when I was blocks away that I realized the no-whip peppermint mocha I’d ordered was actually whipped. But what can you do?
