<p>It depends on the OEM version. No version ships with a MAC, but if one is replacing a computer for example, the install disk that came with it can often, but not always, be used for the MAC. OEM versions can often be picked up in PC stores. The MS OEM license requires a hardware purchase, but that can be a $5 cable, it does not have to be a computer. </p>
<p>Actually, with Apple's free "boot camp" software, Windows does run natively on the new MACs. No virtualization is required. You cannot run OS X and Windows concurrently, however, with this method. One either boots into one operating system or the other, you choose at start-up. This software will be built into the next OS X operating systems (version 10.5, AKA Leapord). Tests by various PC Labs shows that Windows typically runs faster on the new MACs than on similarly configured high-end PC's.</p>
<p>OS X is lacking in a few games and some specialty software for lawyers, dentists, etc. (though they can now run all that software by booting into windows), but only MAC OS X allows one to fully integrate iTunes, Garageband, iPhoto, iMovie, iDVD, iWeb, and iDisk on the lower end and, more complex versions of each at the higher-end. As noted earlier, MS/Office is a nicer implementation on OS X than on Windows, particularly in the area of project management. (I also recommend students get one of the many note taking applications and get Inspiration software [<a href="http://www.inspiration.com/productinfo/inspiration/index.cfm%5D;%5B/url">http://www.inspiration.com/productinfo/inspiration/index.cfm];[/url</a>] available for OS X & Windows.)</p>
<p>The other nice feature of MAC OS X is its ability to automatically detect and configure itself for networks, printers, and other peripherals, and its ability to allow users to easily (and wirelessly even with no base-station) share peripherals with a network connected computer. For example, on trips when wireless is not available, we will connect one computer via a cable, and the others share the Internet wirelessly.</p>
<p>Some of this automatic configuration capability is available for Windows from an Apple software application called Bonjour for Windows. Apple built it so iTunes on the PC would not be limited by the Windows OS.</p>
