While I've only bought around two dozen books from Amazon's Kindle Store, I think I recall at least half of them having jarring typos that totally shatter my sense of immersion time and again.
Imagine being all tensed up reading an intense action scene in a page-turning novel, and suddenly:
"He stretched his arm forward, reaching for die gun..."
Die gun? Really?
I think I've seen cases of "die" replacing "the" in something like a third of my Kindle books. While there are many other types of typos I see in Kindle books, this must be the most frequent.
I don't think the actual books contain these wacky typos. Maybe the publishers are using some German OCR program to make the eBooks?
