Query: Excellent Reading Device with Lots of Potential

I bought the amazon kindle to reduce the number of books I carry around with me and to provide a way to keep all my notes in one place. This device delivers that and more. I enjoy the ability to increase the font on books and the reading option. I hope Amazon will continue to increase its library of available titles and consider ways to publish textbooks in the kindle format. I hope future devices will also be able to render book illustrations, magazine charts, etc.Some suggestions for future kindle devices: (1) bring back the SD Card slot, (2) re-design the joystick button, (3) consider using a cell phone keyboard, and (4) for research purposes it would be helpful to tell what the actual page number is not just a digital location, so one can acurately footnote sources.
