First, check with the school
Before you start shopping, surf to your school’s Web site and find out if the school recommends a specific operating system (Windows or Mac OS). Many students should consider a Mac because they are immune to most of the viruses and worms-a big problem because students often share files among themselves and may have unfiltered connections to the Internet. Business students should stick to Windows, the platform of choice in most business environments. Some engineering programs, such as AutoCAD and Pro/Engineer, are available only for Windows. We prefer the Home Premium version of Windows Vista for its multimedia features.
Arts and sciences majors are probably safe with either Windows or Mac OS. (If you must have the best of both worlds, you can buy a Mac and then install Windows as its secondary operating system.) Macs continue to outrank PCs in security and tech support,
