I fire up VMware fusion to run Outlook 2007 -- I originally thought this was the greatest thing since sliced bread. What I've noticed, however, is the MBP gets noticeably warmer on the back left quadrant, and battery levels drop significantly. As soon as I close the VM, I can tell the machine cooling off and battery performance looks better. Is this just me or are other people noticing this? I do think the overall VMware fusion + outlook integration is awesome, but I think it might just have to hold out until Snow Leopard.
