What actually stops me from buying ebooks:
Availablity: Not all books I want to read are available in digital form
Geographic restrictions: Not all books I want to read are available for my country(ies)
Drm I can't break: If I'm not sure I can break it, I don't buy
Ridiculous prices: self-explanatory
Format: I don't want pdf, for pity's sake!
Quality: If I buy an ebook full of typos and obvious signs of sloppy ocr, I'm just that little more hesitant to spend my money on the next one, especially if from the same publisher.
What helps me enjoy more and better quality ebooks:
