If you read this site on a regular basis, you are no stranger to the fact that publishers are offering all kinds of great deals for Kindle books. It seems that every week there are at least 3 or 4 irresistible deals where a good book is marked down to just two or three dollars. I know that for this reason and others, many of you are considering purchasing a Kindle. I have put together this little guide to help sort out all the options.
In general, there are two advantages to an e-reading device: the price of books and the convenience of the electronic format. Because there is no printing or shipping cost involved, books tend to be significantly cheaper in ebook format. Because ebooks are mere bits and bytes, they weigh nothing and an entire library can be carried wherever a device can go.
Kindle is the leading ebook device and format and the only one I have used extensively, so I will focus only on it (and not on Nook, Kobo and the other variations).
The first thing I will do is run over the options. This seems complex, but only because Amazon offers so many variations on the device. The first three devices are all e-readers, meaning that they have a screen that is not backlit (i.e. you cannot read it in the dark without a light source) and are meant to mimic the experience of ink on paper. They use very little power and need to be recharged only every week or two under normal use. The final option is a tablet computer, similar to a small iPad.
The entry-level Kindle  retails for just $79 for the ad-supported version or $109 with no ads. It weighs just 6 ounces and has enough storage to hold around 1,400 books. This device offers only wifi connectivity, which means that you will need to have a connection to a wireless network or your local computer in order to purchase books or add books from your library.
A word about advertisements: They will appear on the screen when you are not using the device. As you let the Kindle go dormant, the screen will show advertising about products or services that may be of interest to you. There may also be small advertisements when you browse your library. You will not see ads as you read a book.
This is a good option if you are just investigating the market, if budget is a significant consideration, or if you are not much of a note-taker.
Kindle Touch  comes in two models, each of which has two variations. If you would like wifi connectivity only, you will pay $99 for the ad-supported version and $139 for the ad-free. If you would like 3G connectivity, you will pay $149 for the ad-supported version and $189 for the ad-free. Kindle Touch is slightly larger than the base Kindle (half an inch) and 1.5 ounces heavier. The primary advantage it offers is a touch screen, allowing for a more intuitive user experience. It has capacity for around 3,000 books.
In most cases, this is the Kindle I would recommend. Set a budget and buy the best one you can afford.
Kindle Keyboard  is the original Kindle model, though it has been much improved over the years. It comes in two variations, the ad-supported version at $139 and the ad-free at $189. You will also be able to choose between two colors. This version has a small QWERTY keyboard for those who prefer a physical keyboard. It weights 8.5 ounces, is 7.5” high, and holds about 3,500 books.
Kindle Fire  is very different from the other Kindles in that it is a tablet computer rather than an e-reading device, which means that you can use it to check email, surf the web, run apps, and so on. The Fire comes in just one model and it costs $199.
You are now thoroughly confused. So here is what I recommend:
The Kindle Fire is also an option if budget is not an immediate concern. It is quite a good device as long as you let it be a Kindle rather than an iPad. If you compare it to the iPad, you will be disappointed.
