If his point was that digital projection is inferior, fine, I don't think anyone would argue that an XGA resolution projector is going to beat any slide projector.
You got it right. The cave thing was that before starting any kind of X vs. Y comparison, you have to define the purpose for which you want to use them, and please make it a valid one. The kind of testing we see now on most web sites is the "we take a shot with both cameras, then we scan the film, and examine on a computer screen a small detail of the digital image vs. the scanned one". I seriously doubt that this is the way most viewers look at photos, so while the test is a nice technical exercise, it has little meaning. If you tell me "my purpose is 8x10 prints and I took images with both kind of cameras and sent them to my lab and I got better results with X", I won't object, whatever X is (digital or film). Like you didn't object to the conclusion of the test for my purpose.
cheers, caveman
