I have the last gen of the core-duo MBP 17, it has the 2.8 GHZ processor, 8 Gigs or RAM and a solid state drive. For me the answer to your question is no. I would imagine that with the new MBP it would be better but with my set up. I really only have waits on VM boot-up and a lag when I have not used a running VM in a while. Other than that it feels just as responsive when I am actively using the VM. I mainly use it for a windows VM though because I do, do .NET development from time to time. I use my desktop VMWare software to virtualize development OS'es for server VM's I have a server box that runs ESX server, which runs server like the Oracle stack, a VM that runs the IBM stack and one that runs the windows stack. Another note about my setup is that I use VMWare Fusion I used several other products and VMware just seemed to be the most responsive under OSX.
