According to paidcontent.org, Jeff Bezos is bullish on mobile, whether it’s Kindles, smartphones or what he calls the “new category” of wireless tablet computers.

Why?

Amazon customers spent more than $1 billion via mobile device in the past 12 months, including sales by Kindle, and Bezos used the Q2 earnings release to suggest that tablets “over time” could “become a meaningful additional driver for our business.”
