I have lots of shit installed on my computers (no really, shit - not stuff). I don't have problems with, like some people have, Silverlight or whatever people refuse to install for whatever reasons. But one thing I don't have installed is skype. Skype, for some reason, just scares me and doesn't feel right. I can't explain it. I had it installed on one of my laptops while I was travelling heavily and it felt like computer was bogged down by it, even though it had almost nothing installed on it. Call me paranoid - and I never am.
