My guess is that their product will get cheaper and more commoditized, and those 15% profit margins won't last. But I don't know much about the industry -- that's just what happens in tech, in general.
Good product, but there are too many free options out there, and a lot of general turmoil in the virtualization space right now.
The free solutions are getting much better and can compete with VMWare. Furthermore, I would say the money is not in desktop virtualization, but rather in server virtualization. For this, does VMWare even have a product?
Huh? They are extremely strong in data center virtualization - in fact that's where their main revenue comes from: http://www.vmware.com/products/server_virtualization.html
