Look mate, not to be rude or anything, but a little bit of anticipation from your side would be nice. Two questions (actually three) to answer your question: 1. Do you know Google or any other search engine, the one on this site? 2. How big is the plastic theme and how much free space is that going to give you? If you have 0 free space left, would uninstalling just a theme be sufficient, you think? Somehow, from what you wrote, I have gotten the impression that you don't know what kind of machine you have at your hands. Let me tell you, it is a very powerfull little toy you have there, and it can easily be broken. So, do yourself a favor, and start reading up on this purchase you made. Once you get the basics, it will also have taught you how to formulate questions you might want to ask here. Yes, the learning curve is a bit steep, but if you are willing to invest some time in it, learning Linux is one of the best things any computer interested person could do. I said it could easily be broken, right? That was good, but just so you know, with more knowledge it becomes easier to fix what you broke as well.
