The biggest piece of shit in the toilet otherwise known as Microsoft operating systems. It's a magnet for malware, spyware, viruses, etc. A computer running Vista (or Windoze Visuck, as I like to call it) will constantly freeze, crash and do other weird shit that other operating systems don't do.
Oh, and it comes with a lot of bloatware and other stuff you'll never use.
Windows user: Hey, have you tried Windows Vista yet? It's like, totally awesome and so much cheaper than a Mac!!!!
Mac user: I have, and it's SHIT! I don't care if Macs are expensive, you don't have to worry about viruses, bloatware and all the other crap that comes with Vista!
