If you have been looking at the Amazon Kindle then you will find that the Barnes and Noble Nook has many of the same features. So you will find access to a big library which includes thousands of eBooks, newspaper and magazines. You will also get the benefit of built in wireless access but with an added benefit! When you are in a Barnes and Noble stores, you will be able to browse the text of books in full.
Without question what sets the Nook apart from other eBook readers is the color touch screen which makes it more attractive to many. You also get the benefit of an expandable memory which could be incredibly useful if you fill up the memory that is included. The included memory provides the ability to store something in the region of 1,500 books.
The Nook also incorporates various features or functions which really do take it beyond being just an eBook reader. For example you are able to customize your screen savers, create unique photo galleries and read books from local libraries.
One of the really interesting features, which addresses a frustration that I have with the Kindle, is that you can lend eBooks to friends (who have their own Nook) free of charge, for up to 14 days.
That is just like being able to hand a paperback or hardback book you have bought to a friend.
To some extent with the features they have incorporated it was inevitable that Barnes and Noble would have some issues. Users have been quick to let them know about them and Barnes and Noble worked quickly worked to release upgrades that tackled the problems.
One thing you do need to be aware of is that you cannot download eBooks when outside of the US, even with the Wi-Fi connectivity.
Overall, if you want an eBook Reader with additional features such as the color screen and will not want to download eBooks outside of the USA then this could be a definite competitor to the Amazon Kindle.
