On October 31 ( tomorrow ) you can download CodeWeaver's Crossover program for Free for a day. This is a really fantastic program. I personally use it on my Mac to run a couple of Windows programs that simply are not available on the Mac. These programs were not even listed as compatible so the program is more capable that they can say.
It runs the Windows program inside of a Mac Window which is VERY DIFFERENT from dual boot method OR running parallels or other virtualization program.
I actually like the Crossover technique because it makes the programs literally act fairly much like a Mac program.
