never ever had any problems with Windows, if it was shite i wouldn't use it, but it's quick, reliable, compatable with everything i need, regularly updated, safe and easy to use. I can never understand why some people hate windows so much, cracking their nerdy jokes about crashing and stuff, windows is a great OS, if it wasn't it wouldn't be running over half of the worlds computer.
The only way i would get a different OS is if the majority used it, and i needed it in order to do what i wanted to do. In the mean time i'll stick with what i know works.
