hey...i just bought the base model macbook a few days ago. i imported 5000 pictures into iphoto. then when i tried to view them it would lag a LOT. so when i scrolll up or down... you could see the "film roll name" appear...but the pictures were a few seconds behind. do you think this is because of the video card? or do i just need more ram? are there any other photo managing programs that are like picasa. i love how picasa organizes photos. iphoto is horrible.
