Earlier quoted context omitted.
Nintendo has always released low end commodity hardware.
Not quite "always". The N64 particularly was pushing the envelope for consumer hardware at release and both the NES and SNES were quite advanced for their time (though their USA releases lagged quite a bit behind the Japanese/Famicom releases, which means at the time of US release they weren't quite as impressive). They certainly stopped focusing on advanced hardware (in the raw CPU-power sense) post-N64 though.
N64 was a bit more modern, you're correct, because they went with the SGI/MIPS, but I was distracted from Mario 64 by GLQuake 16 player LAN deathmatches, so..
