"I like to download things, but I also like the idea of being able to use multiple machines and have everything — my settings, files, and apps all sync up intelligently. Download an MP3 on one computer and listen to it on another. Version control lets you do that." No, synchronization lets you do that. Version control lets you maintain history about the changes to a file or set of files. They are very different things. Live Mesh, for instance, gives a great sync experience that is pretty much exactly what the poster says he wants, but doesn't have history.
