I've been reeding online books for some years now.

Last time I had a parperback in my hand I couldn"t even read one page.

The page wasn't clean enough, the letters weren't sharp enough, the font wasn't to my liking, pages were to short, background light was't adjusted to what I wanted, the book itself was too heavy to hold whit three fingers....

It was a mess, I still hadn't read that book.
