I've used Ubuntu One in the past, but lately running 12.04 beta Ubuntu One is more in your face now. When I wanted to transfer some files it moved instead on copying them to the storage. Then when I tried to delete them, Ubuntu one still says that I have used 57% of my 5GB. What's wrong with this program? Doesn't it know when there is files there or not? So far I'm not impressed with Ubuntu One until you have some control over it. I'll use something else for cloud storage for now.
