> PDFs and ebook readers are not a good mix. I beg to differ. Maybe PDFs and small-screen eInk readers are not a good mix. For anything technical (computer science/maths) I only buy an eBook if there's a PDF version available (a PDF that looks like the print edition). I've had nothing but bad experience with reflowable formats such as EPUB with technical books. Equations and graphs are stored as low resolution images, any complex layout (floats for example) has to be turned into a strictly linear flow, etc... A vector PDF, on the other hand, is infinitely scalable, so you can zoom in on graphs and equations without any loss of quality.
