My favourite operating system is Windows 98 because it is easy to use, fast, stable, has the MS-DOS prompt unlike Windows ME and is ideal for my website designing and computer programming. I would say that the best operating system is the one that suits your needs and can do what you want it to do and I say stick with Windows or the MACos but not Linux. I say this because the stupid Linux programmers have made it too hard for the average user so I say stick with an easy to use operating system.
