I have been using the Kindle 3 for a couple of months, and also using the iPad to read my Kindle selections, and I wanted to offer a few additional thoughts.
I still enjoy reading my books on the Kindle because of the electronic ink and the lack of backlighting, which makes it much easier on the eyes for long periods of time.
The added weight of the Kindle when in the case with the built-in light has not been noticeable. Folding back the cover when reading works well, so I have not taken it out of the case to read at all.
I do like having the 3G version for both purchasing and previewing new titles, and for using the Web browser anywhere I am. Of course, the iPad wins, hands down, for Web browsing, but the Kindle works in a pinch to check e-mail, tweet, or get ready-reference information. (I am one of those people who feels the need to have access to the Net and information with me 24x7, so I always can make do with the tool I have on hand!)
I have a more complete review of the Kindle 3 here, if you are interested.
Below you will find links to the two versions of the Kindle 3, the WIFi-only and WiFi/3G version and also links to all the apps for reading Kindle books on other devices. One of the main reasons I prefer the Kindle device is the number of titles available in the Kindle bookstore.
