One financial analyst speculates that the Amazon Kindle will do for ebooks what the iPod did for digital music — expand the market enormously.  According to this analyst, Amazon.com could sell more than $2.5 billion in eBooks by 2012.  That’s a lot of eBooks!  And, that’s not even taking into account any boost sales might be by the introduction of an Amazon Kindle 2.0 at some later point.
