At work we use a proprietary Windows only application that is not too much unlike Microsoft Outlook (as an example). It's the only windows software I will need to run on my Mac. My question is what is the best way to run it, so my Mac stays cool, and reliable? I'm not interested in running any of the "free trials" they offer as time is at a premium, as I'm sure it is for you. I'm not opposed to using BootCamp even though it would be dual boot that way. I'm a bit hesitant about VMware or Parallels, for just one application, but open for suggestions. Thanks!
