I’ve had a Kindle 2 since March. I love it to death.
The screen is great for text. Very, very easy on the eyes.
For graphics - less great. I’ve been a bit disappointed in how Kindle handles illustrations - not only is the 16-color greyscale (I think) limited, there also doesn’t seem to be a standard for how Kindle places illustrations. An example - I reread the Chronicles of Narnia on the Kindle. The illustrations sometimes got moved around a bit - I’d have one pop up probably three pages later in the book than it should. This is a publisher issue, not a Kindle one necessarily, but it’s still a distraction.
Battery life is excellent. I probably only have to charge mine every two weeks - charging is only a few hours. As others have pointed out, the big battery draw is the wireless connection, which you can disable at any time.
The Kindle is very comfortable to read. I keep it on my nightstand usually, and read in bed. It’s not very heavy. I’ve also taken it on planes and to restaurants for when I’m dining alone. Also great in coffeeshops.
It seems sturdy enough. I did buy a very pimp case (M-Edge) that protects the screen when I stuff it in my laptop bag. I have to say, I’m not a fan of the sterile, clinical Apple-rip-off white exterior. My lovely case solves this.
I’m not entirely happy with the book selection. I’m a fierce re-reader - I tend to read books I own or have owned several times. So as soon as I got the Kindle I went looking for a bunch of old favorites. Many weren’t available. This is improving constantly, but it’s still a disappointment to read a glowing review then hop on the Kindle and find out it’s not offered. Project Gutenberg is great and I use it, but of course it only has older texts.
The web browser is shit. Don’t waste your time.
My Kindle has crashed three times. It was never a big deal. It takes about 2-3 minutes to reboot. No data lost. It did typically “forget” my current page by maybe three clicks or so. No worries.
I hate the navigation clicker. It’s far too slow to move around in a page - which I most frequently use to highlight a word to look up in the (provided) dictionary. Amazon needs to improve this, and fast.
I’m also a bit disappointed in the page turn/refresh speed. I read at a hellacious speed - not a brag, just a fact. When you click “next page” there is sometimes a few second delay until when the next page actually shows up. I know this is a drawback of the electronic ink the kindle uses, but I’d like to see them speed it up a bit.
Prices on Amazon for most titles are pretty reasonable, IMO. Newer titles are usually $9.99. Older titles are often much cheaper. There’s lots of good free stuff too - browse the “Kindle Favorites” from the storefront, a lot of the most popular items are free. And of course Project Gutenberg and other sites offer more free stuff than you will ever get through.
Other than a few nitpicks (navigation clicker, refresh speed, book availability) I’m a huge fan of my Kindle 2. I’ve read far, far more in these past six months than I have in the last three years. The Kindle is a joy.
