title_body: Are DRM free ebooks considered a better quality ebook? Many authors, editors, and publishers appear to feel they should wrap a DRM around their ebook.  However, a DRM can be removed from an ebook which appears to only cause an annoyance to the purchaser.  That said, do DRM free ebooks provide a better quality to the customer ebook?  Do DRM ebooks cause the ebook to be slower and are there any statistics or tests on an ebook with and without a DRM?
upvoted_answer: This question is a little subjective (is it better) and broad (there are many different DRM formats). 
  
  With that being said, in my personal experience, I prefer DRM-free ebooks. They work better in various readers that support the given document format. I don't always like to use my Sony Reader for books that I purchase (usually epubs). For programming books I often like to use my laptop (either web browser or Calibre) because the programming examples are more difficult to read when shown on a smaller screen that forces line wrapping in unusual places. 
  
  I've also had scenarios where I have bought an epub that only worked properly on a Kobo reader (bought from Chapters). I was forced to remove the DRM protection and manually edit the CSS files and remove some javascript code that was causing the font-size to be so large that the book was illegible.
