Now that people have started using it for a while, has anybody run across any problems with their Copy installation or use?

I'm still trying to figure out the best setup (locate the tar files, and tell it to use another directory? Run it all from one palce?). What setup are you using?

I'm up to 132 GB of space (which is more space than my laptop's hard drive )! I'm just about to turn off my Dropbox account for cross-platform and cross-distro synchronization (leaving Ubuntu One and SkyDrive for OS-specific things like Visual Studio solutions and etc.)
