Well I finally decided to try VMWare. I have been testing stuff for years now by just rebuilding Machines, testing on them and then rebuilding them. It would be nice to test different OSs and programs without having to rebuild my machine over and over. My question is what VMWare version should I be looking for. I want to be able to test different OSs, including Win7 & Mac OSs (Theoretically of coarse) and different apps on them. My machine is a Dell ATG D630, 8gb Ram, 500gb Hard Drive, Core 2 Duo T9300 With XP Pro 64Bit on it (Not sure if any of that makes a difference, but better more info than not enough). VMWare looks expensive, so I am sure I will be exploring other activation options and I am tired of paying for software to be disappointed with it after the 30 Trial is up and I have already bought it. Any Help would be greatly appreciated!!
