OK! Had a go at VM6 using Vista x64 as host and xp pro sp2 as guest.
Heres a 1600x1200 vm window sitting inside my 1600p desktop.(vmware will allow me to increase to that rez though it must be said)

Pros
*easy to setup
*stable
*easy interface
*virtualisation settings tweakable for RAM, HDD, CD, even USB and CPU(can use single or dual core)
*dragging files across from host to guest is flawless and quick
Cons: not a major suprise
*graphics virtualisation limited to 16MB VRAM
(see pic insert which as a config test screen from Kotor 2 inside the xp vm)
Even though it wont allow me to play KOTOR(not my original intention anyway), it DOES allow me to use a video capture software/device that only has x86 drivers - as Im currently in the process of backing alot of VHS porn special memories :D
so vm ware stays on for the moment!!
VERDICT:
They've finally delivered the vmware goodness to x64 peeps !! \o/
