The idea is that the camera is not the profit item, the film is. Just like the old Gillett days. Razors were free, but had to keep buying blades, which were the profit item.
I don't think it would do much for Kodak though, as digital is firmly entrenched. Also, even digital cameras aren't selling as well due to camera phones. I understand the P&S digicam market is shrinking due to phones.
IMHO, there is no profit in the digital camera market. It has shifted to the software and tablet market. I think that's why Kodak shifted to the printer market. Sell printers so you can sell LOTS of cartridges. Unfortunately, they are late in the market which is already saturated. If I was CEO of Kodak, I'd quit - I sure don't know what they can do.
