Just use free virtualbox. Frankly, I dont understand why people buy these things.
I tried VMWare when my company bought me a new MBP, but I get very erratic cursor behavior that just could not be tamed, and VMWare was of no help whatsoever. Tried VirtualBox and everything ran perfectly the first time. And although VirtualBox is free, it has the backing of Oracle.Just use free virtualbox. Frankly, I dont understand why people buy these things.
Personally I prefer Vmware. They have better support, fusion is typically more stable and compatibility with Linux is superior.
Parallels, may be a tad bit faster but its generally a bit more unstable.
VirtualBox, is not bad but the tools provided is subpar, lack of support and has less features then Vmware or parallels typically has me bypassing this alternative.
Parallels is also a dirty app to remove. You actually have to get into terminal and remove stuff manually after looking up guides on the internet ala Windows style. In this sense, you could say the company succeeded in creating a Windows experience right down to the removal.
I actually had to dl the demo of the Lions update just to remove my previous version since the uninstall would not work. Even after the (2) uninstalls, you have to do the finder/terminal hunt for stray files.
