As per the post, each file that is uploaded to Cloudup has a 200MB limit. But each of your 1,000 items can be 200MB in size. That's where the 200GB of potential free space comes from.

I've never used Dropbox but it certainly looks like it's pretty easy to use just like Cloudup. In this case, Automattic owns Cloudup, not Dropbox so that's one distinct advantage.
