We know about the important function of paper cards in the world. When people ask us who our competitors are, we respond with 'paper cards'. The only we we will solve the business card problem is by playing well with these paper cards.
What you see on E today is the basic system we've designed to handle contact information with an additional visual layer. Features to handle paper cards - and mimic paper cards for that matter are things we're working on passionately. We know what it feels like to get a great looking business card, with a nice choice of paper, excellent typography, etc. But I'm convinced in time we will find an equally attractive solution - though it will not be overnight. The transitions from vinyl to cd to mp3, or printed books to ebooks have also take years.
Our added benefits however (stored geolocation of meetings, synched notes, etc.) are features we're getting great feedback on.
