Hello guys. I currently have a 2.4ghz MacBook Pro (with the 2 graphic processors) with the 24inch Apple Cinema Display. I also have an iPad. In the 6months I have had the iPad, i have not moved the macbook pro from its little cubby space thats plugged into the display. (Meaning it has satisfied most of my portable needs) I am thinking about selling the display and mbp for a 21inch iMac. is this a good idea?
