Try Selling Benefits instead of features.
I think this is Marketing 101. People tend to care less about features than they do about benefits. Benefits carry with them more clearly defined value. Chris Guillebeau in "The $100 Startup" writes that people really care about having more of: Love, Money, Acceptance and Free Time, while at the same time wishing for less Stress, Conflict, Hassle and Uncertainty. When showing features, and I do believe that there is still room for them occasionally, be sure to tie them back to benefits where possible.
