I had the new MBP but I returned it because of a dead pixel and got my money back. Now I have this 24-inch iMac that I have had for awhile and I was wondering if I should sell and get the New MBP again.The high end MBP with 2.8ghz 4GB RAM and SSD? Is it worth the upgrade? New iMacs I heard are coming out later anyways so why not?? Help would be appreciated!
