License keys don’t need to be boring text strings. All the data contained within the license key can be kept in a beautiful image. Drag-and-drop defines the Mac. We do not want people trying to type the license key by hand; images can be dragged and dropped with ease.
This idea is Mac-only for the time being, but it’s cool to see. The scenario would be installing a new piece of software, and dragging the graphic to your license manager, instead of typing in a huge serial key. I understand how this may benefit downloadable software, but what about all the boxed software you buy?
