If there was a service that did it for me I might do it.
I have one book that a friend scanned & OCR'd for me & I've messed with it a bit, but each chapter is basically just line after line of text so I've had to go in and put it into paragraphs using the pbook as a guide. After two chapters I decided there were better ways to spend my time. I'm sure I'll mess with it again sometime & do a few more chapters and quit again.
The do it yourself digitizing thing's definitely not my cup of tea. I've got over 2,000 fiction books & hundreds of non-fiction books. I'd love to have at least the fiction all in e-form, but figure it'll never really happen.
