If more memory is required you may take a look at the Essentials package, which removes these limitations.
You just told me in in one sentence what I needed to know. Show me anywhere where it tells me that http://www.vmware.com/products/datacenter-virtualization/vsphere/pricing.html here. People would buy it at $495 and $65 for maintenance if it can save them from buying another computer. It doesn't take a calculator to determine it has a good ROI.
If VMware can't explain the capabilities they are selling in simple terms, then they need to illustrate it with scenarios and capabilities, not acronyms that I have no interest in learning until AFTER I know if their product is cost effective for my environment. Skip the green talk, reduced electricity, building space, and A/C costs. The first thing on my mind when I hear that is they don't have a business case. It needs to be real, and it needs to be clear. This is what you would buy from Dell instead of that. This is what you save, and this is how much we charge. Also, this is what you could do with our product that you cannot do without it, and this is what that costs. If the ROI isn't that clear, there isn't any. If they use a case study, it has to be real, not same ones I've heard over and over where I pretend to believe what only salesman could believe.
