I bought an ebook (of Nurk by Ursula Vernon) assuming it was a COMIC like her other things. It’s actually a story with illustrations, which would be fine except they didn’t include the illustrations in the ebook. I just get [Image]. Not even a frickin’ image description.
(Seriously go read Digger, though.)
Edit: the illustrations appear in the Nook mobile app but not the online reader. They’re also DRM’d, so the only way I can read them on my laptop is through their online reader (and the only way I can read them on my iPod is by downloading a special Nook app), not in Calibre or the new iBooks app.
I’m never buing Nook ebooks again.
Amazon at least has a free Kindle reading app that works offline. And I’m not 100% sure– I don’t remember whether I actually bought my .mobi books from Amazon, or whether I downloaded them from somewhere else– but I don’t think the ones I have are DRM’d, either.
