Riding the tram, there was an ad of sth. interesting sticked to the door. The URL and a QR code were printed at the bottom. Instead of opening the browser and typing in the URL on the shaky train I fired up the Goggles app (home screen), pointed it to the code and about 2 seconds and one button later the page was loading in my browser. Given an URL and a QR code above I would always choose to use the QR code just because it's much easier than using the tiny on-screen keyboard of the smartphone. QR codes should not try to replace an URL but rather be an alternative to typing it in. You could compare that to whatever.com (not hyperlinked, type in/copy paste) vs. http://whatever.com/ http://whatever.com/ (hyperlinked, one click).
