Just imagine having 7 seconds (because it is about Windows 7) to show some new feature in your new product. In some of them they also had a time to finish their coffees and all of them were „visibly surprised“ by the request „show me what is new“.
OK, it is probably nothing extra superb, but definitely something people will share and easily remember. As I did and now I’m using some of those features really often.
Search for them on YouTube.
