The reasons I use VMWare Fusion are:<p>1. VirtualBox shared folders performance is terrible.<p>2. VMWare Fusion is the only shared folders implementation I&#x27;ve found (tried Parallels, VirtualBox, and VMWare Fusion) that can follow symbolic links, making them look like normal files&#x2F;directories on the guest (useful for Windows guests which don&#x27;t understand nix symlinks).<p>3. IIS can&#x27;t host applications off of VirtualBox shared folders for some permissions reason, which cannot be fixed.<p>I really hope VMWare Fusion doesn&#x27;t die, as it&#x27;s the only product I&#x27;ve found that supports my use case.
