thats not true. i have duel monitor 24". say im editing a picture with photoshop. i can have the orginal on one screen and edit on the other. i can see the difference. On the other hand for conversation. i dont print many documents while trying to follow the instructions. instead of printing for example. i can bring up a manual in pdf for a program on one screen. start the program on the other and follow the instructions. very nice for that. editing mostly in CS, macro assembly on one screen and a symbolic debugger on the other screen while trying to fix my problems. works well. i think others have a use for it also.
