Oh, I'm not saying the Wii's Bluetooth was inadequate or anything (at least, I never had any issues with it). "Bluetooth 20 years ago" just prompted me to think about what sort of Bluetooth devices were around 20 years ago, and I realized the Wii comes very close to fitting that bill (and I guess was actually using a version that is now 20 years old). And then I felt old.
