Dell 24" in the office at 1920 x 1200 and when on laptop 17" at 1600 x 1200. I wouldn't go back to regular work on less than 24" as the extra space is perfect for all the menus. I think at the distance I work from the screen (optimized to the focal length of my computer glasses) a 30" would give too much side to side wiplash.
