Well, I like it because: 1. It looks cool. Clearly identified as a medical item. 2. It's for people who don't have a computer (they do exist, doc!) or have a Mac. Like moi. 3. Even for people with a PC, it probably has a complete template, so if a person is not medically sophisticated they can just fill in the blanks.
I like it. However, I'm still relying on a little piece of paper in my wallet. That's cheap and really easy to "download."
