I spent last week in Boston, attending the Open Mobile Alliance meeting. Whenever one goes to meetings, one does the dance of the business card exchange. Because it was my first OMA meeting, I had more of it going on than usual, as I met a lot of people for the first time. So I’ve collected a batch of 2-inch × 3.5-inch cards, which I then have to copy information from and put it into my address book. And there’s no hope of reading these things without my reading glasses.They’re inconvenient, to be sure, but they do work, and we’re used to them. Everyone has them.
