I just bought an I7 iMac and was excited to run it with my 24" cinema display. Now that I have it all set up I'm not really sure why I would need it. I have 12 screens using spaces on the iMac and at the moment primarily just keep Mail open on the second screen which is convenient, but I am trying to rationalize the loss of desk space vs the "cool" factor of having the second screen. What do you guys use the second screen for? What am I missing? Thanks for your opinions.
