I personally don't, but I do know people who like the "flash full power straight to your face and the result is grainy" -thing.
I remember my father bringing back a polaroid camera from work in the eighties. It was amazing. Snap, a blank photo rolls out and a few seconds later the image appears. I can see the magic of that. At the time it was innovative because until then, you had to use film. Wait for the film roll to fill up, it to be developed and printed, etc. There would be days/weeks in between taking the photo and seeing the photo.
I think the process is the bit that's magical and what appeals most to people; not the esthetics. Which are indeed a bit meh. You get a not so great photo instantly. It's not the same when you use a great digital camera to take a photo, then make it look like crap with some filters to emulate the polaroid look, and then print it on a high quality printer. It's much easier and it should replicate the esthetics perfectly. But without the old school process it just isn't the same.
For any single producer your statement is true of course, if they raise prices of people will just buy from the other producers. But for the product at large the price should (with perfect competition) stabilise at a point where all the producers would make more if they all increased prices together (so consumers are actually willing to pay more, but because of competition the price is lower).
