<p>There is no software that will not run on the new Macs. Some of the best software, the iLife applications for example, will not run on Windows. Macs are the only computers that will run Mac OS X, Linux, and Windows XP operating systems. Parallel Workstations $50 virtualization software allows one to run Windows XP/Vista currently with Mac OS X at near native speeds (why anyone would want to is beyond me). Macs are currently virus free, no ad-ware, and have the very best everyday software. The built-in iSight camera is a nice touch as well. Student purchasers get a nice discount when purchasing Macs.</p>
