Introverted book-lover seeks compact gadget to contain her ever-growing library. Gadget should be easy on the eyes and the wallet. Should also be slim and portable. Must be cross-compatible with other e-reading technologies in case book-lover gets fickle and decides to upgrade gadget to something new in a few years. Gadget should also feature some sort of note-taking or comment-writing function. Wireless technology and sizable storage space a plus.
