Choice time
bootcamp works, it's free and supports all the goodies like accelerated video for furtive windows gaming. Downside? Well, you have to shellout/reboot into Windows.
However, 80 bucks gets you Parallels Desktop for Mac: a system designed from the outset to upset tall sandwich
You get multi platform support while still in the mac operating system. If you've got the originals you can run every flavour of Windows including Vista, linux distros, BSD, Solaris, MS-Dos 6.22 even OS2

seamlessly.
Click on an application and it opens natively right there on your Mac desktop. Doesn't suport accel video yet though so said furtive gaming is out till next upgrade.
Saving on frigging about makes option 2 the one for the folks in my situation. We run our Boeing BLT and Jepp software faster on the Macs than the extremely expensive native Windows tablets on the flightdeck. Perfect for us but your mileage may vary.
