Simpler technology usually means fewer things that can fail, tbh. I expect my Gameboy will probably outlast my GBA-SP which, in turn, should outlast both my DS-L and 3DS (and, technically, if you count that I broke the chassis on my first DS-L, it kinda already has -- although that wasn't mechanical failure, that was just clumsiness).
Even the older consoles have all sorts of things that go wrong with them. Good luck finding a secondhand atari or nes that actually works. Its possible, but most of them need components replaced.
By "original" do you mean from the first issue? ---
