Currently running Macbook Pro 13" Late 2009 Model, with the 9400M graphic card. Lion runs ok with the system (probably because I recently upgraded to a 7200 rpm). The problem is how laggy mission control is whenever ANYTHING is running on the background. I miss those smooth animations in Snow Leopard, especially for expose. Does anyone know if this could be fixed in the future from updates, or does my graphic chip really just can't handle the aqua animations.
