Hey guys. I've searched quite a bit on this subjact to no avail. I currently use mobipocket to read ebooks and its great except for one thing. I am an engineer and there are a lot of technical articles that get sent to me that I read. They are in pdf format and contain equations with a lot of subscripts and random variables that mobipocket does not recognize when I try to convert them. My first question is whether there is a way to improve upon the mobipocket convertion. If not is there any software that will allow me to read pdfs like and ebook and bookmark pages and such? I need to store them on an SD card due to space restrictions so I cannot just email them to myself. Thanks in advance for any help.
