So, been thinking that I want to get a separate, dedicated ebook reader like a Kindle or a Nook for a few reasons, not least of which is the undeniable truth that the screens on these dedicated readers are much easier on the eye than the iPad for long reading sessions. Also, I would feel a little more comfortable taking a $180-ish device more places than a device that cost me what the iPad cost me. Anyone have both? Do you feel like you have redundant devices? Do you feel like you have the best of both worlds?
