I installed VMWare, I started to create some virtual machines as my test box. Some software I am not sure what kind of performance impact to my pc. Normally, I will try to install that into a text box first. But now, I can create a text box within my main pc as an isolated environment by virutalization. In this way, that is more environmental friendly, less pc (Well, only used my old pc as a test box.)Anyway, I can consider to give away some test boxes.
