I've repeatedly made a bad experience with computer science related books on my Kindle, so I've switched back to books on paper for now. Almost always code is not formatted properly... Maybe simply the format is not suitable at all and other e-book readers are better?<p>That said sometimes also the printed books I buy from Amazon for instance have a bad print (I've had O'Reilly books whereas the letters were not printed properly, such as letters were not properly black / not enough ink used during the print!?). Other times illustrations are supposed to be colored, but the books are printed in black & white...
