Agloves - Touchscreen gloves that are made with silver throughout so that the entire glove is a conductive surface, not just the finger tips.
BassBuds - Beautiful noise isolating in-earphones with Swarovski Elements that also include a microphone and MP3 controller. What a great gift for teen and tween girls.
Brookstone - Okay, this is a store, not a gadget. However I found so many great gifts there this year that I couldn't recommend only one. My favorites are the Brookstone Wireless TV Headphones (you will really enjoy this when your teen is playing loud video games) and the Brookstone Portable iPad Speaker Docking Station (both a speaker and charger).
epillow - The perfect and most comfortable way to hold your iPad, eReader or any type of tablet for any length of time. Many colors available, girls will love this.
Kingston Wi-Drive - This small gadget allows teens to share media from an iPhone, iPad or iPod Touch with two friends at a time. It also gives you additional storage space on your apple device.
Portable speakers - BoomBotix Wireless Bluetooth Speakers are adorable for tweens. HMDX Audio: Jam Wireless Portable speakers come in many colors and great for any age. Both are small enough to carry around.
OWI Robotic Arm Edge. Put it together and then control it.
Tablet - Laptops and cell phones have become must haves for teens. While a tablet has not reached that stage yet, it is a highly desired device by both teens and tweens. The two that I would most highly recommend are the Apple iPad Mini and the Microsoft Surface. However these are expensive. If looking for something more reasonably priced then check out the Kindle Fire.
TomTom - If you have teens that have reached driving age, a GPS device is a great gift. Not only will they love it, but you can worry less. Getting lost is not conducive to safe driving.
