Many public domain books/classics are available for free via amazon. some libraries lend ebooks.
If you're an avid reader, it might be worth it.
Might? Why only might? Is there something about the Kindle, such as price, that would make me regret the purchase? While on a limited budget, I am willing to cut back on certain activities/things for awhile in order to make this purchase but I would like to have the full picture before committing.
