Ah, thanks for the insight. I currently use Boot Camp for personal stuff but find myself needed a VM for previously stated reasons.I am liking Parallels more than VM right now, but Boot Camp is compelling.
VM Ware does not support Vista. Reading the specs, it sounds like version 1.0 will be pretty basic. Fusion only support DX 8.1 video.
For demanding apps, I would rather have Boot Camp. It is full blown Windows w/o compromises. Besides The $99 for Parallels will be better put towards Leopard.
