Perhaps it's worth noting that Kodak now provides "curved field" 
projection lenses as standard for normal (cardboard, presumably) 
mounted slides in their Carousel projectors, but their older "flat 
field" design is recommended for glass mounted transparencies. The 
current plastic mounts allow the film to "float" in part to minimize 
popping, so there is less bowing. The differences are easy to see in 
projection, and also frustrating since my college's slide library 
intermixes all three types of mounts.
