Virtual Box or Boot Camp and What Flavor of Windows?

[gabester]

I have used Boot Camp, Parallels, VMWare Fusion, and VBox. Boot Camp has the advantage of being native hardware execution, but is the most cumbersome for occasional Windows usage. Parallels is supposed to have the best integration with Mac OS - i.e. making the execution of Windows apps seem almost transparent and like a part of OS X - better for a highly task oriented workflow requiring OS X and Windows. VMWare I've found to be more reliable, and really, I prefer the discrete separation of primary OS and virtual OS. VBox is pretty good as a free alternative but is not terribly user friendly and has very little in the way of OS integration.

I've used CrossOver to a limited extent and find it satisfactory if somewhat cumbersome, WHEN things work for it.

Its going to depend on your needs.
