I disagree. You only have to compare your product to what prospective users are currently using. For a lot of products, the most common answers are nothing, email and Excel. It's hard for technical founders to accept that people may choose your product for reasons other than it's the "best". For the user the only delta that matters is quality of life before and after using your product, even if there are ten better products out there.
