A handful of code in iTunes 10.5 beta 9 suggests that Apple may soon start allowing customers to rent apps from the App store, according to The Tech Erra. If a rental system were put into place, it could cut down on money spent on apps that customers never use, which could reduce resentment customers feel toward developers when an app doesn’t work the way they thought it would.
A few strings in the iTunes beta code appear to be pop-up messages to notify customers about the state of rented apps: "Apps are automatically removed from your iTunes library at the end of the rental period" and "This app will be deleted from your computer" are a couple of the included statements.
A rental system through the App Store would be similar to the try-before-you-buy program that Amazon currently offers in its own Android Appstore. None of the language uncovered in the iTunes beta indicates whether rentals would carry a price or be free for their limited run.
via Ars Technica – Report: iTunes beta suggests app rentals may be in iOS’s future. A rental system would be nice, I hate buying apps that I try out and then get rid of. I wouldn’t mind paying say half or less of the normal price and then paying the remainder if I decided to outright buy the app.
