Disclamer: This is not a provided device from Amazon. This is my device that I bought. I feel like I have to say this with so many bloggers now being paid to do product reviews which, IMHO, is absurd. At any rate...
Years ago I got a Kindle 2nd Edition, the second white one, and immediately fell in love with it. Aside from my phone, it was the one device that was always with me on every trip and anytime I had to wait (doctor appointment, car service, etc). I wasn't much of a reader before I got it, but immediately started reading for pleasure a lot more. I also get the Wall Street Journal delivered to it automatically every morning thanks to the included 3G connection. When I wasn't in range of the 3G connection (such as traveling overseas), I could download the latest issue and transfer it via USB. Lately this Kindle's battery was not lasting a whole day so I'd turn on the 3G connection, sync for the latest paper, then turn it off. Even with this approach the charge was a fraction of what it used to be.
Then a while ago when Amazon announced the Kindle Paperwhite, I jumped and upgraded. I got the Amazon stock cover/case which is great as it doesn't add much size to it and automatically turns on/off when you open/close the case. I love the Paperwhite. The lit screen is awesome... no more clip on light. The size is perfect... it fits perfectly in the back pocket of my jeans. I was a bit skeptical about the touch screen but it is very responsive but not too much so. I do, on occasion, inadvertently turn the page, but it isn't a big deal.
I've seen others gripe (namely the incredibly quirky and picky Scott Hanselman) about a few things with this device. First the uneven lighting at the bottom of the screen. Trust me, it isn't an issue at all. It isn't perfect, but you paid only $119 for the device... not saying it is a compromise, but really? If you buy a Honda Civic, which is a great car, do you have any room to complain about the pickup or how it's noisy at 90mph? He also took issue with the screen brightness control saying you either have it all the way on/off. Really... guess you haven't flown much at night or try to read with someone sleeping next to you. I move mine around a good bit... but rarely to the 100% brightness position.
I elected to get the wifi only subsidized with ads version for $119. The ads aren't intrusive at all and I don't miss 3G at all.
This is the perfect eReader. I don't like reading on a back-lit screen and have the Kindle app on my desktop & tablet. The Kindle device is for reading articles and novels. It isn't good for reference (tech) stuff; that is where the Kindle app for the desktop & tablet comes in very handy.
Two thumbs up for me... highly recommended.
