I love my new Paperwhite Kindle! The screen is so fantastic, it's a joy to read on it in any light. When I bought it a few months ago, instead of buying the fancy leather cover, I got a simple slipcase, that was much cheaper, because I figured now that the device itself had its own light, it didn't need the fancy cover. Previous Kindle models solved the problem of the need for light by offering a cover with a light in the top, that the Kindle fit into snugly; this allowed the light to run off the Kindle's battery. It was convenient, but getting the Kindle in and out of the case was a pain, so mostly I read with the Kindle in its case even when I didn't need the built-in light.
One reason I got the slipcase cover was so I could read with just the device in my hand; that lets me take advantage of how incredibly light the Paperwhite is, compared to my old Kindle Touch in its case with the built-in light. And then Amazon sent me a coupon offering 40% off on selected Kindle accessories, and one of them was the Paperwhite magnetic case (sadly, only in black). It was such a good deal, I figured it was time to see if the case was worth the added weight,
It so is! When you open the magnetic case, the Kindle comes awake instantly! It feels more like reading an actual electronic book when the Kindle lights up as soon as you open the cover. Ditto when you finish reading, all you have to do is close the case. The only downside is, that if you want to take the Paperwhite out of the magnetic case, it is almost as difficult as it was to get the Touch out of the lighted case.
Now if they could just make a dual screen version, it would look a lot the the readers in some of my novels.
