New VMWare is pretty nice

I have put myself on a self teaching course to get my skills up to date, and VMWare is a great tool to experiment with different OSs. I've installed and use Windows 2003 Server evaluation, and plan to install FreeBSD, Linux, and maybe Solaris 10. VMWare is *fast*!. It's not simply a virtual machine, it's a hardware virtualizer. Programs are executed natively inside the vm, and only when a program executes supervisor instructions or accesses the hardware does the VM need to intervene. I love not having to dual boot and partition drives and all that mess.
