Carr’s argument is, in part, that the music industry is already doing this: buy the atoms (the physical copy) get the bits (the digital copy). It is also, in part, the sense that many of us have: why do I have to pay twice for the same content?
I am a big fan of both [Pragmatic Programmers][pp] and [O’Reilly][op] because both will bundle bits with atoms, or atoms with bits, for a discount that varies by title. In fact, O’Reilly deserves an especial tip of the hat for their recent move to make buying eBook versions of some of my shelf favorites so easy and so affordable. ($5 for a number of my favorite titles.)
Sometimes I want paper, sometimes I want my phone or my Kindle or my computer. The publishers that give me that choice will quickly become my favorites. (And so I am buying more books from [O’Reilly][op] in particular.)
