Which Is The Best Operating System Currently n Use?

The best OS to use depends on what you are going to use it for. Many if not most programers would use a Unix or PC based OS before using an Apple OS. The majority of graphic designers use Apple's OS and apples software. Now if you are talking about servers then it depends on the purpose of the server. Maybe you run lotus notes, or some other purchased application. Then the vendor would likley require a certain OS (or maybe give a choice of one or two). Microsoft, Sun, Apple and many others have Operating Systems that can be purchased. Each serves its own purpose, you have to figure out yours.
