Honestly, I think the difference is how much software is in these things now. Everything is a computer. And software is something that is very cheap to do half-assed, but expensive to do well (and reliably).

TVs are a perfect example of this. The TV of 40 years ago had an analog tuner directly attached to a CRT. It did only one thing, and did it well. Today’s TVs are basically embedded computers with large screens. And the embedded software was probably written by the lowest bidder.
