I had the same opinion as you, until I saw the results of the human
factors investigation.

This investigation found the following results:

		User interface		User interface
		single string		form-fill-in
	       +---------------------+---------------------+
Business card: ! Not reasonable      ! Very good, but too  !
Full labelled  !                     ! spacious on the     !
format         !                     ! business card       !
               +---------------------+---------------------+
Business card: ! Bad results         ! Very good           !
Abbreviated    !                     !                     !
labelled format!                     !                     !
               +---------------------+---------------------+
Business card: ! Not as bad, but not ! Not reasonable      !
Concise format ! very good either    !                     !
               +---------------------+---------------------+

So the human factors study did find that the best combination
was to have a ***different*** format on the business card
and in the user interface!!
