Amazon Prime: Kindle Lending Service

For all of you Amazon members who have have Prime membership passes, this is for you.

You can now borrow Kindle books for FREE! They currently have around 5,000 to choose from including 100 of that being New York Times Bestsellers. To do this you go through the Kindle Owners Lending Library. There are no due dates, though you are only able to have 1 book out at a time.

Prime Membership costs $79.00 a year. Although if you're a student you can get it at a discounted rate of $39.00 a year here.

I'm officially thinking about getting the service now, although if I were to go with the Kindle Fire this Christmas... I probably would anyway.
What do you guys think?
