I use and love OSX on my iMac c2d. But in my career I need to run a windows program at home for familiarization and to make training materials. What is your choice for the best way to do this? The reboot program available for free, then run win xp pro and my software program or parallels. I know nothing about which way gives the most satisfying experience. The program is an alarm company central station monitoring application which runs in a windows XP environment. Thanks all.
