Seth Godin writes good stuff... I nearly always nod and learn something when reading his blog... he's made an audio file of his latest book and is selling it for US$1 on itunes, and audible is offering it for 'free' as a promotion.
But it's not free at all... it's locked up in some DRM windows / mac only encumbered cage and I can't download it and listen to it at all... well I probably can with some tricksy technological protection measure circumvention wizardry... but that would be illegal.
So nope. Not free. Sorry Seth.
As there's no iTunes for Linux either I can't even get the 'cheap' version.
And Audible.com SUX! No option for Linux at all. Get with the program people
