That will be very specific to each business and each consumer.

A person who likes to play poker online will care about bitcoin different from the next person.

Plus, many of the advantages that should be here now with Bitcoin are still out of reach.  For instance, merchants can pass along their savings when accepting Bitcoin by offering a discount for that payment method and gain a competitive advantage.  But few do this today.   But if a customer was offered a 3% discount on the bill if paid using bitcoins, that alone might be enough to cause the average consumer to want to use Bitcoin.  But today the cost to acquire coins (via exchange) offsets that gain and thus offers no economic incentive.

The Bitcoin Education Project might be a resource that will help in this area:
