Though VMWare and Microsoft now offer free virtualization software, Enterprise Edition of Microsoft Windows Server 2003 runs $3,700.00. The standard Edition runs about 1/4 of that, ofcourse you need to spend a few extra dollars on Client Access Licenses. However, if you should happen to decide you have the need for 4 Windows 2003 Servers, each for light applications, your interest would be better to go for the Enterprise Edition on a single box and cluster the services accross to a fail over box. I can't remember how Microsoft ruled on that particular item.
If the fact that 4 of my servers listed in ZDnet forums were each independantly licensed, I would consider Virtualization an option, but since this is not the case, I am better to stick with my current situation.
Saddening too, I could easily pull a 3 GHz Processor and put in a couple of Dual Cores and push the processing power of that system by about 3 fold or more.
