The biggest difference between an ebook and a paper book? The sound they make when they hit the floor after you fall asleep reading.
@MichaelPryor Question: are ebook readers waterproof?

Because I read in the bathtub at least an hour a day. All my books have warped pages and the soft covers are curling up and peeling.

But they're MY books, so I don't care.

I can still read a wet book.

@MichaelPryor I had to close 4 nagging pop-ups to find out they're sold out.

I'll stick with paper, thanks.
