I was just looking at ELO's touchscreens and was thinking the same thing about that 42". The only thing about it is the resolution is very low for a screen that large. The maximum resolution is 1360 x 768. The cool thing is the brightness is 550 cd/m2 so it would be great in sunlight. Side wall mount it in a tricked out van, that would be sick. I'm still trying to figure out how to squeeze a 15" touchscreen in my S-10 Blazer, I want to upgrade from the 10.2" Xenarc.
