i have no experience with the 2007 but i have had the 2407 for a while, and quite frankly it is disappointing as a photo editing screen. i use monaco x-rite to calibrate, and a ihave a 24-inch samsung as well. the difference is night and day in terms of calibration. the dell is just too damn bright. the dell screen is great for real estate, but not for photo editing work.
