Nice to have is a luxury - it doesn't solve any actual problem people have, it just make life a little bit nicer. Need is an actual value proposition - people are already spending time or money to do a thing that you can do better. I think you're using the rigid definition of "need" like the bottom of the Maslow hierarchy, but in the business world "need" is more value driven, or in the B2C side closer to the top of the hierarchy.
