I downloaded Amazon Kindle for PC and am delighted. It isn't necessary to own a hand held Kindle to read the books that are available. You can download a Kindle on your PC and read Kindle books on it.
There are free books and then there are best sellers. The best sellers are cheaper than print books, about $9.99 some are less and a few are more. It's an exciting adventure I'm on and looking forward to putting some of my own writing on Kindle.
I can get Dan Brown's 'The Lost Symbol' for $9.60--downloaded to my Kindle. The print book on Amazon is $29.95
A feature I found interesting is that Paulo Coelho has decided to make 17 of his books, including the iconic O Alquimista (The Alchemist), available exclusively on Kindle.
I am currently waiting to see when Annon's Secret Something Within is available on Kindle. I made the price remarkable low.
Check it out. I have a link on the top left. See if it's for you.
