They're machines. Why would they need a soul?
And sorry but, if it's a choice between lugging three or four heavy lumps of wood pulp on holiday or a small plastic device that gives me access to thousands of books, I'll take the latter.
It depends, doesn't it. If you're going on holiday, I'd probably agree. However, if I'm reading at home or on the train to work, then give me a proper book any day. For me it's more than just reading and imagination. Other senses are involved too. The feel of the book in your hands, turning the pages, the smell of the book etc. Plus I find reading from a screen makes my eyes tired.
