Windows Vista, the most unreliable operating system ever. It makes your PC lag like hell and it causes bugs and viruses. It is a living parasite that uses up all the memory. IT SUCKS XPs BALLZ!!!! here are some of the reasons why it sucks, now these are just some of them.

3) It's incredibly slow and unreliable, not as slow as PS3 but still.
