It is getting late, but I thought I would post this quick one for you…VMWare is now giving away ESXi for free.
If you never have used it before, it is a version of VMWare that runs as its own operating system…and under 32MB of ram! (This is really simplistic by I think you know what I mean)
I can tell already that this is the shot fired back at Microsoft for their release of Hyper-V
Here is the press release:

I will try it out and let you know how it works out.
Here is the download link for those who do not want to read through the wordy press release
