Now that e-book readers no longer suck as much as they once did, all sorts of people are prophesying the death of the physical book. Nicholas Negroponte told the Techonomy Conference in Lake Tahoe, CA, that paper books were already dead, and people just don't realize it. "It's happening. It not happening in 10 years. It's happening in 5 years," he added. But over at Crunchgear, Devin Coldeway explains why it may take a whole lot longer than that. And of course, physical books won't ever really die, they'll just experience the same transformation that's already hit magazines — they'll become luxury items. Coldeway's whole essay is worth checking out. [Crunchgear]
