Amazon S3 or CloudFront! Why I need Two?

If you got question after reading my previous post regarding Cloudfront implementation then this link - S3 and CloudFront difference is for you.

For me, I do not need Amazon S3 and cloudfront is enough. With all new browsers using 4-6 simultaneous download compared to earlier only 2 download, I think even CDN is not required for websites with not so many images or external resources.
