If you have a mixed network like I do sometimes you have to compromise. At my job we run Windows, Linux and a sole Mac (Graphics dept.) and lets face it, when you do consulting work and if you design and develop custom applications you have to be able to develop for your clients platform and as much as I hate it, it's a Windows world. Before I used to have 2 workstations, one Windows and one Linux, or I had to dual boot. In the past, virtual machines have been lacking. Either they were too slow or lacking a certain pizazz to get the job done. Enter
VMWare Workstation 4.
vmware is also great for help desks, testing out boot discs without rebooting, testing out networks without 2 computers, surfing the web in a safe "cocoon" that you can just trash or set back to a certain state if things screw up and trying out freeware/shareware to see if you trust it to be on your main OS, without worrying about it screwing your main OS.
