But that's not really how books work though. I don't ever really need to read more than 1 book at a time. I'm all for e-readers, have a couple and use them, but it's a cost saving measure. I would vastly prefer physical books for the interface.
Wow, a lot of people taking me very literally. Most people take their phones everywhere, giving them instant access to just about every book ever created. You don’t need a light to read. You just need that thing you already have in your pocket.
Reading books on a phone is even worse than an e-reader though. The difference is usability. It's kind of like saying "Why bother bringing a chair, you have an ass you can sit on anywhere?"
