DropBox: Syncing files & folders between multiple computers

DropBox came out with a new file/folder syncing service that simply trumps any of the competition. Over the past six years I have tried many different syncing services, as many of my clients have desired to easily share files between multiple computers. However, in my pursuits I have never found a service that was really easy to use, for both myself and the potential client.
Finally, about 6 months ago I heard about DropBox, which at the time was still in Beta--and actually still is. (UPDATE: It is out of Beta) However, after watching the demonstration video on the website, I instantly fell in love.

Basically, DropBox creates a new folder in your MY DOCUMENTS directory, which acts like any other folder. Except, anything you do inside of that directory, also occurs on every other computer you've synced DropBox with. For example, if you throw some music in the DropBox folder, instantly the music appears on all the other machines. If you rename a file, instantly the file is renamed on all the other computers. Another cool feature of DropBox is its recovery tool. Basically, if you ever delete or overwrite something, with just a few clicks of the mouse DropBox allows you to go back to any previous version--Beautiful!
I have about 2-3GB worth of data on my Dropbox account and am currently syncing that folder between 3 Mac's and 2 PC's, one running XP and the other running Vista. It works flawlessly. Many times have I been working on a document at work, closed out of it early, then picked up from where I left off at home or on my laptop. The syncing occurs instantaneously and doesn't require any extra effort from the user.
As of today the service is still in Beta and is "Invite Only". If you want access to the service, post a comment and I will get back to you with an invite.

UPDATE: The service is out of Beta and can be joined by anyone.
