You never have to type anything with bump, and you get the entire contact info, image and everything. No way does SMS or typing out an email do the same thing. Even typing in bump into the app store and starting it for the first time to send a contact is less work than writing an email. Touch app store, touch search "bu.." there it is, install, share address, touch phones boom done. It probably takes about as many touches just to get into the email composer.
