The main advantage of VMWare Workstation 5.5 is the snapshot functionality. You can create unlimited snapshots of the VM at will (both running and powered down). So for example, install OS: snapshot 1, install Office XP: snapshot 2, now boot snapshot 1 and install Office 2003: snapshot 3. Get the idea? This saves a lot of time and diskspace (only the differences between snapshots are actually stored). The VMWare server product only supports 1 snapshot at the same time.
