Currently using a 2.16ghz C2D MacBook (GMA950, Leopard , 2gb Ram) with a 20 ACD, in closed lid mode. I notice that some of the animations (specifically expose) run quite poorly - stutters, dropped frames etc. Looking to buy a 2ghz Mini to hook up to the ACD. Aside from the slight speed difference, the specs are the same does this mean that Im likely to experience the same graphic stutters? Its not a deal breaker, but Id like to know in advance if any one with a Mini/20ACD combo experiences this. Cheers.
