Ubuntu One

I have put my files on Ubuntu One.  What is Ubuntu One, you ask? (That's right, I can hear your thoughts).  The new Ubuntu release (9.10, or Karmic Koala) comes with a folder that is connected to an online storage account.  Whichever files you put in the folder are also synched with the online storage account.  Now suppose I have 2 computers, my laptop and a desktop.  Both are running the latest Ubuntu.  They both will have the special synched folder, so suddenly I can work with those files on my desktop, and then the next day when I decide to work at Caribou on my laptop the files are there on my laptop as if the synched folder is the same across all of my computers.

So it feels like there is one folder, and that folder is the same in all of your computers.  Add, remove, or update files from this computer, and then see those changes on the synched folder of another computer as if it is the same folder.  I can't explain it exactly right, but it is really cool so far.  One folder, so it is called Ubuntu One.
