So VMWare have been rather kind and released ESXi as a free download. This is pretty cool and makes me wonder if it's worth installing on every new machine we purchase by default. The additional flexibility of being able to add additional VM's to any low utilisation machine on a whim is rather appealing and the thin nature of ESXi means the performance penalty should be negligible even if it's never used.
I've never played with ESXi before and am interested to see how it stacks up against Xen and VMWare Server. Now to find a suitable guinea pig machine...
