So I already have a UMB 2.0 from last fall and I have started to do a good amount of photo editing with Aperture and CS4. I already upgraded my ram to 4 GB, but I feel like I need more screen space. My Mac seems to be running slightly sluggish when I run Aperture and Photoshop but that might be because my hard drive is almost full. I certainly would love the processor bump in the iMac but I know it doesn't have the LED display and I've read all the problems about the iMac displays. Should I sell my Macbook and upgrade to an iMac, or should I get a 24" ACD, or should I just wait and see if Apple releases a new iMac with an LED display?
