Since posting Responsive Web Design: Missing the Point and For A Future Friendly Web, I’ve gotten quite a few requests to use a few of my images for presentations and posts. I think these three images succinctly explain why we need to start thinking in a future-friendly way. So here they are in their original format, free for you to use.
