What is Dropbox?
Dropbox is a desktop application (for Windows and Mac OS X) and storage service that just works. It's the easiest way to share and store files online and keep files in sync across your computers (
quick video demo here).

The beta is still invite-only, but we're no longer keeping the details under wraps -- and you're welcome to invite up to 10 friends to the service (they'll be able to download Dropbox too.)
You're also welcome (and encouraged!) to blog about your impressions, post screenshots and discuss Dropbox wherever you'd like.
Thank you
Your thoughts are always welcome. You can reach us by visiting the the beta forums after signing up or by email at

Enjoy!

So, I thought this was pretty cool and wanted to share with you all.
Dropbox - Home - Secure backup, sync and sharing made easy.
Here is what it looks like on your computer. The folder "testing out a test" is a folder I am sharing with my friend. I put a picture in there, and he edited it and put it back in there, and it synced up.

This is what it looks like when you log in their website.

If you click on a file, it gives you the history of that file.

And this is what the icon looks like on the almighty apple menu bar.
