Hey there... I am using my Macbook with Vista... it works wonderfully! I only had to install Vista coz my Engineering course needed some AutoCAD, and 3D Solidworks software.. which I couldn't get hold of for Mac... Window's Aero works beautifully... my Lowest base score is 2.3... but the rest are high.. all above 4.5.

My specs are Core Duo 2.0Ghz... 1GB 667MHz DDRII SDRAM... 120GB SATA... (40GB for vista)...

Windows Vista Ultimate btw...
