Firstly, well done to Haderer for predicting the dawn of laptop cafe culture. Walk into any branch of Starbucks in a busy city around lunchtime, and this is exactly what they look like. Busy workers, checking emails and dealing with minor tasks whilst they're on the go. Smartphones and devices have made us free to work wherever we are. Because we're free to work wherever we are, perhaps we work when we shouldn't. We're still figuring that out as a society.
The gentlemen reading the newspaper, though, is old. Everyone looks at him with astonishment. Newspaper readers in cafes are now outnumbered - the last of a dying breed - and the picture may be a comment on the death of the printed press. That's OK, though. That's progress. You can't stand in the way of it!
