and close your account seems to be a strong point of DropBox and Google. Of course, we can assume that when you remove your data it still may be archived somewhere else on the hosted solution's servers... but the ability to remove the copies of files from *my* drive is important to me.

Right now I know I've got about 450 songs that I did not know were in Microsoft's cloud on their servers. I don't know where, I don't know how they got there, and I don't know how to manage them. I vaguely remember doing something with either XBox Live or Windows Media Player, probably several years ago - and maybe it is something that I can remove if I want to, but finding information on it is difficult. I don't feel that Microsoft has the same kind of maturity with dealing with large scale consumer demands on cloud solutions as Google.
