Apple's Mac OS X operating system has seized 6.22 percent of internet usage share for January 2007. The company's Mac OS share climbed to 6.22 percent, up from 5.67 percent in December of 2006 and 4.21 percent in January of last year. Apple's Intel-based Mac OS X internet share rose one-tenth of a percent to 1.88 percent from 1.77 percent in December of last year, while its PowerPC-based Mac share rose .19-percent to 4.35 percent from 4.15 percent in December. Apple's expanding internet share is credited to several factors, including the disputed iPod 'halo' effect -- where customers purchase iPods, exposing them to Mac systems as an alternative to Windows PCs -- as well as the company's Boot Camp software enabling Intel Mac users to reboot into a Microsoft Windows installation on a separate portion of the hard drive. Windows XP holds just over 85 percent of the operating system market, followed by Windows 2000 at 4.93 percent. Windows Vista, which just recently began shipping, gathered 0.18 percent share.
