The only regular use I ever have for QR codes is loading a long page url I'm looking at on my desktop to my phone. I keep a chrome plugin installed so I can click a button for a QR code. Beyond that, I'm not going to some random link encoded in a QR code.

If you use Chrome or Firefox, they have browser sync to their mobile apps now. You could also employ Instapaper or ReadItLater/Pocket and just click the bookmarklet.

Scanning a QR code sounds like it may take some time if you're in a rush.
