L O LThese ads seem to target Beats-wearing hipsters / college dropouts that rather live in Twitter and FaceBook than in an office environment. So that's the target market. They have variable jobs that pay less, can't afford a house or a car, work from Capuccino-bars. Their only time-critical transaction is calling an Über to get their next interim-job. So understandibly, there is little time to open a laptop-clamp which is too heavy anyway. It might damage their newest sneakers. This is the category Apple calls "Pro" - without designating a specific area of workmanship.
They probably don't know what an envelope is - so forget your tweet.
