Ubuntu One helps you store, sync and share .. UbuntuOne is the latest offering from Canonical to help you sync your file and share them easily without much hassel..
Currenlty the service is in Beta mode so if you are interested you can test it out and give them feedback on improving it further... Ubuntu one aims to be powerful and yet simple to use.. Built on the same ideology of dropbox Ubuntuone seems to have less offering at the moment than dropbox but as I said it is still in testing phase so hold your breath till the fruit matures..
For higher upgrades and space you need to pay inorder to get the extra benefit but if you don't have much to sync the free service is there for you.. It seems Canonical is going to up the ante and turn the tables to everyone whether its Linux distro provider or its mammoths like MS and Apple
As of now ubuntuone is invitation based so if you want to test it out get an invitation https://ubuntuone.com/auth/login/?next=/invitation/1/request/
