How does the "Device" information help on the reports?

It is useful to know which devices are scanning the code because web pages may look different on them. They may look very similar, but as I’m sure you’ve seen or heard in the commercials, the Droid smart phone does some things that the iPhone doesn’t (and vice versa). So, if the reports told you that 90% of your scans came on the iPhone, you certainly would want to make sure that you have tested a video or web page on that type of phone.
