Stressed out? Who isn't, what with everyone trying to get a ton of stuff done before the holiday. Wouldn't it be great if you could get your hands on a gadget designed to drain your tension away? Well, the emWave Pocket Stress Reliever probably isn't it. Placing your thumb on its sensor, the 2-ounce device will display your level of "coherence" — a measure of how efficient and "in sync" your body's systems are — so it's probably more accurately called a stress detector. Hmm… am I stressed? Let me check this gadget to find out. The relief part apparently comes when you fire up the included software, which includes a coherence "coach" that teaches you various techniques of chilling out while using the emWave. That all sounds fine, but for $200? Just think of all the yoga classes that would buy you. — Peter Pachal
