Well, I work at a convention center doing (among other things) AV setup. A VGA output would enable me to test the connection between the lectern computer and the projector. We use VGA at 1024x768 as standard on multiple brands of projectors. While I in no way expect that resolution, even 640x480 would enable me to test that all the colors work.
Anything between epson's and sanyo's up to Barco's and Christie's. Though more often that not we use cat5 or fiber for the big boys.
A VGA out would save me carrying a VGA tester or Laptop to each room.
How convieniant would that be?
