While some hiccups are to be expected in the transition to ebooks, I think the most disheartening is the response of the vendors. When readers reported many similar ocr errors in the french ebook
L'élégance du hérisson, the publisher (Gallimard) corrected them and allowed all purchasers to redownload the new version of the text for free. A little show of good will like that will go a long way to making people want to buy more ebooks, even if the texts are not all perfect at first. (of course, if you ask me, it was the least Gallimard could do, particularly as they are selling that ebook for 19€, while the paper editions costs the same.
)
I hope that both french and german publishers will soon make better efforts in their digital offers ; in the end, this sort of attitude only will hurt themselves, in the long run.
