No longer were PCs and Macs incompatible at a very low level. Indeed, Macs are now simply PCs running a different operating system. This fascinating change opened up the possibility of Mac users running Windows software natively on their machines, either in a dual-boot scenario or, perhaps, in a virtualized environment that would offer much better performance than the Power PCÃ¢â‚¬â€œbased virtualized environments of the past. These dreams quickly became reality. Apple created software called [COLOR=blue !important][COLOR=blue !important]Boot [COLOR=blue !important]Camp[/COLOR][/COLOR][/COLOR] that now enables Mac users to dual-boot between Mac OS X (Leopard or higher) and Windows XP, Vista or 7. And enterprising tech pioneers such as VMware and Parallels have created seamless virtualization environments for Mac OS X that enable Mac users to run popular Windows applications alongside Mac-only software such as iLife. Now consumers can choose a best-of-both-worlds solution that combines Apple's highly regarded (if expensive) hardware with the compatibility and software-library depth of Windows. Indeed, I've been using an Apple Macbook notebook running Windows 7 ever since Microsoft's latest operating system shipped in early beta form.
