Barne's N Noble just released their brand new E-reader called the Nook. It looks really promising and has some amazing features like color touch screen, wi-fi support, free 3g, pdf support and an SD slot. It almost has convinced me to buy one and I am a hard sell because I love real books. There are a few reviews at the nook homepage below. They rave about it calling it out of kindle's league.

Until it is released we won't know for sure. At the moment the Kindle 2 owns the lions share of the market. The Nook comes out next Tuesday (27th) according to the web.

From my personal experience, the Amazon Kindle is the best.  Even the oldest model is easy to use, convenient, and compact.  I've tried other similar devices at book stores, but none are as easy to figure out quickly.  With the Kindle, there are also tons of books to choose from as well as newspapers and magazines.  I highly recommend it!

This has a lot to do with preference. If you really care about being able to buy books wirelessly, then you might go for the Kindle or Nook. If not, then you could be happy with the Sony Readers.

I have the Sony Reader and one of the main reasons I like is that I love the e-ink screen and the variety of formats that it supports.

Finding the best e-reader is a matter of opinion. There are resources online where you can compare the ratings given to the top ten best e-readers available at this time. The match up compares several different factors that are important to consumers. The website with the top ten review of e-readers is in the citation field below.

I bought my mom the Kindle for her birthday.  I think it's great.  It's very easy to read and very small.  It also has a lot of books that are available for it for lower prices.

I personally like the kindle better than the nook right now. However, both are great! Below is the a comparison between the two. 

NOOK

The Good: Includes an additional color screen, permits friends to borrow downloaded books from one another, and allows free browsing of entire books when the user is in a Barnes & Noble store.
The Bad: Slow to boot up, format text, and display it on the screen. Color screen and Wi-Fi connection drain battery life.

KINDLE

The Good: Lighter and faster than the Nook, it boasts longer battery life, and each of its features has been thoroughly tested in the market.
The Bad: The physical keyboard seems clunky and unnecessary. And it lacks some clever features, such as lending rights.

I purchased my Nook for my husband last February and he loves it. He has swapped with Kindle users for test drives and found that the Nook is less cumbersome to use. Some of the kindle users preferred the Nook once they tried it.
