Many business users opt for PC notebooks because the dominant operating system, Microsoft's Windows, cannot be used on a Macintosh computer. This dominance makes it easier to swap files with other businesses, to find compatible printers while on the road, to interface with the computer systems of clients or customers, and to find useful software since more software has been written for the PC environment. You greatly prefer the functionality of the Mac operating system over Windows Bear in mind that Macs and PCs are not completely incompatible. Today's Macs can, in fact, read PC disks in their floppy drives.
Software is also available to translate most files without too much hassle.
Some software also allows Mac notebooks to run Windows software, albeit more slowly and with a greater chance of compatibility problems. With respect to configurations, Macs are based on the PowerPC processor, the fastest of which is the G4. Currently, Macintosh notebooks, called PowerBooks, use the older generation PowerPC processor, the G3, which is available in speeds of 400 and 500 MHz. Other than the processor, issues surrounding the configuration of a Mac notebook are essentially the same as those surrounding configuration of PC notebooks. The exception is that all new G3 PowerBooks come with a DVD drive, which can read both CDs and DVDs.
