Agreed. The difference between "how easy it is to share a link on S3" and on Dropbox is a million miles. Sure, actually sharing the link on S3 is easy, but getting the file onto S3, setting up security buckets, yadda yadda is non-trivial to low-tech users.

With Dropbox, I basically put a file in a folder.

There's always a market for convenience.
