Oh well. Just means I am more likely to use Audible.com. Faster. Cheaper if I don't want too many new books at a time. And considerably less space than the CDs.
But, no, my dears, it won't replace physical books. Now, those awesome (and very expensive) little digital 'book' readers, that you load text data to? Oh my. THOSE might just replace the physical books. Oh, yes. But not today, nor tomorrow. But soon, I think. Soon.
