Parallels is very nice, and I can't think of anything wrong with it really. But since my trial key expires today I thought I'd give VMware Fusion (Beta) a try (expires May 25). Parallels does have some things that Fusion does not have at this point. But what I like with Fusion is that the rest of my Mac seems to be much faster (same RAM settings on each). With Parallels I just about have to quit everything on the Mac side, and when switching between Mac and Windows my MacBooks drive sounds like it's doing a lot of swapping, etc. That doesn't seem to be the case with VMware - even though debugging is on. Does VMware have better memory management or something? Why would my Mac environment seem faster when running Fusion, and slower when running Parallels?
