If you think of what you could do for $200 last year vs today, I could argue the prices went down.

Yes I agree with this - models today are better than they were a year ago. But not sure if I can "do for $1 what used to cost $25" across the board (meaning two times occurred 5x price reduction). But it's maybe not that simple to compare as there are some simple things also that just were not feasibly possible at all some time ago.
