I agree. . . that's why I commented that MacDonald's Burgers probably would be more in the running. . . but then they were consumable. If, however, you look at non-consumable, single maker, specific products, Horace Dediu is probably right. I've been trying to think of one that might meet that criteria and cannot. I did get out the popcorn while I watch you guys rise to the challenge though.
