Kindle Phone? Amazon CEO: 'Stay Tuned'

Amazon CEO Jeff Bezos discusses how Amazon makes money off of Kindles, which is one of the key differentiators between Amazon and its competitors, like Apple. As to whether a phone is in the company's future, Bezos won't say one way or another. Bezos seems skeptical of same-day deliveries, but is optimistic about opening retail stores — but only if they're better than existing retail stores.
