I just discovered Asus webstorage when I bought a Asus transformer. The software seems a whole lot better than dropbox or google drive and it can't hurt to have another place to store your files.
If you sign up via the following link I get a extra 512mb storage: https://service.asuswebstorage.com/referrals/b9IsJKqNtkYw684…
In what way is it better than dropbox?
