I was a VM Fusion user and then had to update due to new MAC Pro. Fusion would not work so I had to load Parallels and I am so glad that Fusion did not work. Parallels works so much easier and more efficiently that Fusion ever did. I know that Apple has done quite a bit of work on battery life but Fusion would drain my battery in ~45 minutes when it was launched even if I was not using it. Parallels, and the new MAC I can run for hours and not have to plug in. Parallels is much easier to use and does not have any of the glitches that Fusion had.
