iPhone Business Cards

This is a business card design for someone that i found on swiss-miss' blog. Its taking something that everyone is familiar with, i know in every one of my classes i see at least 5 people with their iPhones on their desks. The benefit to a business card is sticking out among all the other plain business cards. However these are full color, have gradients and are two sided and appear to be larger than a regular business card; so they must be very expensive. Theyre must be a balance between these two aspects, the cost and the ability to stand out. If you can afford it, it might be worth it. Otherwise youre stuck with a much simpler business card.
