In the interest of full disclosure:
I worked at EMC in 2004 when they bought VMware, and therefore had access to NFR ESX licenses and obviously had access to storage.
I left there in mid 2006 to work for a weather data company, think Weather Channel, but more commercial customers.
I left them earlier this year work at the local storage division of one of the big IT vendors. This puts me in contact with VMware, while my cow-orks a few cubes over handle MS & Hyper-V.
