Sony Portable Reader System PRS-500

Electronic gadgets allow you to do all sorts of things that weren’t possible not that long ago: You can listen to music, hold conversations, and surf the web while you’re on the go.

The Sony Reader now adds digital reading to the list. This portable reading device displays a wide variety of e-formats and holds up to 80 books in its memory (and more if you add removable memory cards).

The Portable Reader weighs in at a light nine ounces, and it’s compact, measuring just under five by seven inches mall enough to fit in the palm of your hand.
