It might be business customers are more willing to jump through hoops. My website is targeted at the general public in a small midwestern town, where technology is a four letter word.

Indeed. Business customers aren't representative of the greater public because they tend to take their issues directly to IT support, they get it sorted, and don't think about it again. Your every day average user doesn't have an IT support department to which to go. They do, however, have the App Store/Play Store.
