Example of selling benefits
Here is an example of selling benefits instead of features. Show people what they can do better, instead of what your application can do.
From Highrise blog:
You don’t need another address book; you need a way to keep potential deals from falling through the cracks. You don’t need another email client; you need to get better at meeting new customers. You don’t need another todo list; you need more time with your family. Software should simplify the jobs we have, so we can spend our time where it matters.
