Free vs. Paid apps in the Android Market: This is a problem…

On Buying And Selling Apps | Smarterware

“Android users don’t already have their credit card information entered into Google Checkout (or is it Wallet), so the difference between downloading a free app versus buying an app is the inconvenience of setting that all up. Since apps are often impulse buys, and typing your credit card information into a form on a touchscreen handset is annoying, it’s easier for an app-buying virgin to pass, or decide to put it off till later… indefinitely. My own wife hasn’t bought my Android app on her phone because she hasn’t gotten around to setting up her Google Checkout account yet. For a year.”
