If you’re an iPhone developer, you’re faced with a tough problem. You have to differentiate your app from the 25,000+ other apps in the app store, many of which solve the same problem that your creation purports to solve, and convince people that they really do want to spend their money (and their time) on your app.

Let’s face it, selling is hard. Really hard. You can try and list out features and benefits, or you can focus on the beautiful design of your product, or, if you’re Sandwich Dynamics, you can just make a lighthearted joke out of your new iPhone app as a way to introduce it and explain what it is and what it does.

The beauty of the video is that by the end of it you feel as if you are watching a couple friends goofing off. They are genuine and genuinely funny – which makes it much easier for you to open your wallet. Which illustrates an often forgotten, but tremendously important, point about selling. If you treat your customers as friends, instead of users, you’ll not only have an easier time making the original sale, but an easier time throughout the entire customer life cycle.
