I am about to buy a macbook pro 13", I fell in love with the screensize, weight and everything else. The only thing that bothers me is that its a little sluggish when it comes to graphics. I mean, the dock and the grid for example... They are so much smoother n the 15" ! I know it has a dedicated video, but still, shouldnt a 1280x800 resolution run smoother with a 320M? Is it a hardware limitation or just bad graphics drivers ?
