Responsive Web Design and Development

We have been doing a lot of web development recently that has a responsive design as well.  It seems the trend to do a mobile friendly website (more a microsite) is fading away fast and our clients are starting to consider responsive as the primary alternative.  We were recently forwarded this article by one of our partners and thought it was worth sharing with everyone else.
You can see several different responsive sites and how they work with your web browser.  Try opening up a few with your mobile phone to see how they compare in functionality to the full site too.
