How to run PC apps on your intel Mac?

I recently had a need to run some PC apps on my iMac. I know thee are many ways to do this, but I came accross this simple program called Crossover (http://www.codeweavers.com/products/cxmac/) that really makes it easy without the huge overhead of running a VM. I don't think this would be good for all programs, but it might just be what you need. It's fast and easy to setup. They also have a version specifically for PC games. I haven't tried this but I do have a few games that are beckoning to be tested. :)
