Being fair, I've never found a paper book without at least one typo either. Hell, I accidentally bought a paperback on sale that had the last 100 pages replaced with another copy of the previous 100 pages.
In my experience print editors are far more receptive of being informed of errors than ebook editors --- often an ebook seems not to have had an editor at all, certainly no one proofread the copy of _Space Cadet_ I bought on the Sony ebook store for my Sony PRS-505 --- it was so rife with errors as to be unreadable, and required that I borrow a print edition from a local library so as to be able to send in the corrections.
