Free!

Chris Anderson wrote an excellent article how scarcity is replaced by abundance. And he lives what he preaches: his new book "Free: the future of a radical price" can be downloaded as an audiobook for free from here.
Even better: the full text and the audiobook in the full version (free) and an abridged version (not free!) are here.
If you are like me an iPhone/Touch/Pod addict, you will want to hear this as an audiobook and not just as a collection of MP3s. I Used "Mp3 to iPod Audio Book Converter" to convert the MP3s into an audiobook. It's free (of course) and does this job very easily. Recommended!
