If you get the Kindle from Amazon, you have 30 days to return it, paying only postage.
Gives you plenty of time to use, download, and see how it works for you.
As for library usage......do you belong to a library that carries a selection of ebooks you are interested in? Not all libraries are created equal. It will do you no good to have a reader that allows for library downloads if your library isn't well stocked.
If it is....thats another story.
