Exactly my point!
Pro version is for hire only. No permanent license exists.
I now switched for VMWare Fusion and I'm very happy with it.
MY SQL database is happily running with 32GB virtual memory 
This is what I found so far:
The negative sides of VMWare:
1) lack of MAPI mail integration
2) 32 bit Linux cannot be installed with 64 bit CPU
But I can live with them since:
1) I found gmail plugin for Windows (tvhgooglemapi) to handle MAPI
2) If I really need to install 32bit Linux, I simply fire up VirtualBox (freeware)
The positive sides of VMWare:
1) 48 Euro price tag for a personal license (i.e., multiple Mac installation allowed)
2) very generos 64GB RAM + 16 CPU limit
3) virtual machine can be run under all other VMWare products for Windows, Linux as well as vSphare hypervisor.
Saying that, the largest reason I decided to walk away from Parallels was lost confidence in their business practice.
I cannot entrust my production environment for the software
which hangs my system and demands a payment during the routine minor version up.
