When shopping, look for a reader that is not back-lit as these are harder on your eyes than an e-reader. E-readers now have built-in lights which can make reading in the dark fairly comfortable if that's where you like to read. Before buying, check with your public library about on-line books as most now have free book downloads that you can borrow like at a regular library. You will have more options through your library, but not all readers are compatible. And finally, watch the weight. Most readers are now very light, but if you want a case it will add weight. The lighter the better. I don't keep mine in a case, but do slip it into a zip-pocket case when I take it away from home. Enjoy!
