Dan Frommer has an interesting article up over on Quartz that makes the observation that Apple’s been designing, and releasing, wearables for years. They may not be what we would classify as a wearable today, but devices like the original iPod Shuffle could offer a lot of clues about what Apple may be working on these days in its wearable department.

It’s an interesting take, albeit a modest one. It’s worth giving it a quick read.
