I got the Kindle 3 wi-fi in graphite. It is sleek, attractive, and has a really nice feel to it. The screen is just beautiful, and I love reading it and looking at the pictures when I put it into sleep mode. It was easy to use right out of the box. It came with simple instructions on how to plug it in.
The only snag I ran into was hooking it up to the wireless network in our house. I had to wait for my husband to get home to ask him where the password was. After trying to input the password several times, he realized that we had too many devices hooked up to our network. He disconnected the Wii, and the Kindle was good to go. It quickly downloaded several books I had "sent" to it from my Amazon account.
I originally felt like I would continue to use the library and buy used books when it would save me money. Now, I am thinking that I will be a little more choosey with my purchases and perhaps read mostly on the Kindle. I actually regret buying a couple of used books recently--I wish I would have waited so that I could read them on the Kindle instead.
I find that I read faster, that it is easier to hold than a traditional book. I love how I don't have to dog-ear pages. I am constantly being interrupted by my children while I read, and the Kindle keeps my place.
So, after one day of owning a Kindle, I can say I am very happy with my purchase! I will post again in about a month (hopefully) to report on how I am enjoying it (or not) at that time.
