Thank you, Anaamika, for giving me another opportunity to wax about my Kindle. 
I’ve had my Kindle DX since June of 2009, so a little over a year now, and absolutely love it. I also have an iPad, which has made me appreciate my Kindle even more.
The only issue I have is that I spend more money on books now than before I had the Kindle, and that’s even with the Kindle discount. As I said in another thread, it’s simply too convenient to buy books with the thing.
I would seriously consider getting the Wi-Fi/3G version as opposed to the Wi-Fi only version. The $50 more for the 3G version is definitely worth it. I can’t tell you how many times I’ve wanted/needed to be able to download books while away from home or other wi-fi source and was thankfully able to. The advantage of Amazon’s 3G network is there’s no monthly fee, and no payment plan. I think I’ll repeat that. There Is No Monthly Fee Or Payment Plan required to access Amazon’s Whispernet network. It’s free. Gratis. And you can use it twenty-four hours a day if you want. Before I purchased my Kindle, I also believed there’d be no need to download books while away from home. Boy was I wrong. I now can’t imagine having to be tethered to a single spot to get my fix of tomeage. 
Things I love:
Battery life - Amazing. I can read for weeks without recharging. Also, perhaps I haven’t had it long enough to experience any degradation, but battery life seems to be just as long as the day I received it 15 months ago.
Non glare screen - Again, amazing. I can read in bright sunlight without having to orient the device so the sun doesn’t hit it.
Weight - I have the DX, which is larger than the standard sized version, but I find it to be very manageable. Also, it is less than half the weight of the iPad, which has almost the exact same dimensions.
Eye strain - Absolutely none. I can read, and have read, for hours at a time with no problem at all.
Non Amazon books - There are many online outlets with books in Kindle format, some of which are free, so you’re not locked into Amazon’s bookstore. This is great for obscure books or books from non established authors.
Things I don’t love:
Book availability - Although Amazon adds thousands of books monthly, that certain books I want are not yet available for the kindle still makes me frown, although there are conversion tools available for books in other ebook formats.
The experimental web browser (yes, there is one) - You can browse the web on the Kindle. It’s kind of cumbersome because of the lack of a pointing device but, in a pinch, it gets the job done.
Search Utility - This could have been implemented so much better. I’m actually hoping for a firmware update to resolve its deficiencies. Again, it gets the job done, but there are not enough tools to refine a search.
Color of device - When I purchased my Kindle, it was only available in white, which is terrible and shows every smudge. I have since purchased a black skin, which is good, but not a fantastic solution because I can see having to replace the skin every so often. Amazon now offers both the standard Kindle and the DX in a graphite color. Seethe…
I love my Kindle so much that I take it practically everywhere I go. I fly a lot for work, and I never have to worry about running out of reading material on flights anymore. Get it. You will love it too!
