I think this is too vague of a opinion on virtualization use. I think it depends on what you're doing with it. VirtualBox is a nice piece of software for desktop/power user use, however, ESXi and ESX are geared more towards enterprise and business critical use. So, it kind of depends on what you're going to be doing with it. Regards, Max
