This is what we all agree on: they are different.
What's stupid is to fake digital into film. You know? To say that digital is film. You know? That a D750 sensor is kodak tri-x.
Yes, they are different and I do both.
On second point, I'm not sure if I agree 100%. Say I am a digital only photographer. All of my gear are digital. Say I don't want to get another body for a project. I don't have a darkroom and don't have mini-lab nearby. If I want to make an image that will pass as an old fashion film image just for fun or to mass consumers, what am I to do?
APUG is an enthusiast site, so I see what you are saying. But many products are made to appeal to masses. Professional photographers sell to masses. They only need to please masses' taste and senses in exchange for their money. Wedding photographers couldn't care less about what's pure or if grain looks like Tri-X or HP5.
If I can tell the consumer, "you know, I can also make this look like an "old-school" film photo for 10 dollars more, would you like that?" I think I would.
I think this kind of product does have a purpose. Perhaps not for you and I and for majority of APUG. Many consumers, hobbyists, professionals, studio/wedding clients simply don't care about details, and they are the majority.
