Wow Apple introduces a new concept apart from other Apple gadgets like Apple Laptops, Apple iPods, Apple iPads, Apple Mobile, Apple iPhone and Apple Apple and Apple etc but now what Apple presents is really a unique idea of controlling your Apple iPod with just one finger that is Apple iRing that can sense, control your functions through it's very special feature none other than touch sensitive.
Basically what is the feature at back-head is the concept of using Bluetooth through this you can tackle Apple media features playback features like play, stop, pause, rewind, forward by just pressing an invisible button. It can also support OLED status display with touch sensitive strip other than this you can adjust volume control as well. Unfortunately or fortunately it looks amazing at female hands not on males ;) So guys why not you think to gift it to your girlfriends but don't forget to gift iPod as well because it's useless without it :P
I have another idea you can also use this Apple iRing as gift of Apple Engagement iRing.
