Next, about a year after it came out, I bought what Amazon called the "Kindle Keyboard" and was hooked! I began using the Kindle as a preferred reading medium over physical books and thought that the Kindle Keyboard couldn't be improved upon (I've since given a couple as gifts). I liked the storage capacity, the 3G capability and thought I wouldn't want to be without the keyboard. After reading more than seventy books on it I couldn't imagine trying a Kindle with less memory and only Wi-fi.
I was wrong.
I ordered this "4th Generation" Kindle earlier this year, thinking I'd have it for a backup to my Kindle Keyboard. Instead, it has become my much-preferred device. Storage room? With the cloud, it's really not an issue. I keep a few reference books on both of my current Kindles (the Keyboard and this one) as well as what I'm currently reading. I haven't had any problem with coming close to exceeding the storage capacity. While it would be nice to have 3G, it's not a deal-killer at all. I've already read close to 50 books on this Kindle and I've only found myself without easy access to Wi-fi once. When I'm close to finishing a book, I plan ahead and download a new one (or two) so that I'm ready wherever I happen to be.
I also thought the cover for the Kindle Keyboard was better, but have found that I like the (Amazon official) cover for this one every bit as much or better. I don't need an elastic band to hold it closed (thought I wanted this, but it is really a non-issue). I flip it open, flip it closed, leave it folded back and just generally don't worry about it. That's what a cover should be - unobtrusive.
The thing that makes this Kindle a real winner is its size and simplicity. It's easy to read one handed in any of the chairs in our house, at the island in the kitchen, at a restaurant at lunch or while lying in bed. It fits easily in my pants pocket, in a briefcase, laptop case, accordion file, sportcoat pocket, etc.
The battery life (with "airplane mode" on - meaning Wi-fi off) is fantastic. I read anywhere from a couple of hours to as many as seven or eight hours per day and I generally can go three weeks (never less than two) between charges. I turn on Wi-fi (or turn off "Airplane Mode") to download new books or to allow sync'ing with other devices (I'll still use the Kindle app on the iPad when reading in the dark), and unless I forget and leave it on, the battery life is just fantastic. I also like the fact that charging just involves hooking it to a USB port on my laptop or desktop. I wouldn't mind having a way to know the percentage of battery life left, but estimating from the icon I'd say that I have at least 20% battery life and I've read several books since the last recharge going on three weeks ago now. Oh, and the time to re-charge from a depleted battery is only a couple of hours at most.
Will I try the new "Paperwhite" with 3G? Probably. Will I miss the page turn buttons? Maybe. Maybe not. I thought the 2nd gen Kindle was where I'd stop (I even thought about buying a second one because I "liked it best"). The same was true with the Kindle Keyboard. Again, I thought it was the best version and wouldn't be improved upon (and once again considered buying a backup in that version). Today, I'm on this product page because the announcement of the Paperwhite made me think that maybe I should buy another one of the "Kindle 4" devices as a backup.
Then I remembered the other two times I considered stocking up on the "tested and true" versions and decided to write this review instead. Maybe this will end up being my favorite Kindle. But if it doesn't, if the Paperwhite or even one of the Kindle Fires becomes a new favorite, I'll have paid my due respects to a device that has given me a great deal of pleasure.
I recommend this Kindle without reservation.
UPDATE: I've uploaded a video showing the Kindle being used one-handed. It's a little shaky (using the other hand to try to hold the camera), but shows the Kindle being used left-handed to "turn" the pages. From the other reviews I've read this doesn't suit everyone - I guess it's a matter of the size and shape of each person's hands. The video also gives some sense of the page refresh. I've uploaded a couple of still shots in the photo section at the top of the page that provide an idea of the resolution.
