This is true of the 2.0 film?
Well, Impossible HAD to make the new SX-70 film work in the original SX-70 camera which does not have a film speed selector. That camera was designed to work with slow "film".
As for expense, Polarioid was always that way. I could only afford a couple packs at a time... On one trip, when Polaroid film was still available for it, I brought an SX-70 to the trailhead of a long backpacking trip. I shot the whole pack the first day before we set out, and I sent off "Postcards" to folks back home. The shots were soft and impressionistic. Creeks, trees, rocks, that sort of stuff. Some people thought they saw a bear in one of my shots but it was just a funky shadow.
Anyway, since it weighs a couple pounds I left it at the trailhead and shot 35mm film for the rest of the trip.
You have to think of the result as miniature works of art. One time I saw a wall of SX-70 photos on display at a candy shop in Northern California. The photos were all original and had reasonable prices (I think around $25).
I always was envious of Andy Warhol, because he was provided (and he consumed) a practically unlimited supply of Polaroid pack film. Though I thought what he did with the "Big Shot" camera was odd, endless ugly pictures of celebrities...
