I used to use DesktopX a year ago. At first, it's nice because the interface is entirely customisable and you can do cool stuff with it. But eventually I kept getting sick of the themes because of the poor design. Proper interfaces take years of research by very bright people before they are released to the public. DesktopX themes are just pretty backgrounds/folders that you can put shortcuts on. None of them are really intuitive enough to use as an interface though. This is why after a couple months of using DesktopX, I reverted back to the standard Windows desktop and found it alot more intuitive to use, even though things aren't necessarily where I want them.
