Apple has introduced a new "App-Enabled Accessories" category of goodies to the online Apple store and it's a veritable one-stop shopping destination for the geek on your list.
There's so much to peruse here, like the iOS-ready Philips Hue light bulbs and the super cool Parrot AR.Drone 2.0. You'll also find health products, things for music and more.
A quick note to my family: I'll gladly accept pretty much anything on this page.
