We're at CES Unveiled in Las Vegas, and just had a chance to take a look at BodyMedia's new Core 2 health and fitness monitor. The company is hailing the device's sleek form factor — it's much smaller than its older Link and Core monitors — and its new size allows it to quickly change appearance with snap-on faceplates, armbands, and cuffs. The smaller size alsop BodyMedia says the Core 2, like its existing devices, can capture over 5,000 data points per minute with a variety of sensors that can detect a user's temperature, heart rate, and other biometric data. The Core 2 will release in August, and while the company doesn't have a firm price yet, it says it should be comparable to its Link and Core devices, which top out at $119.
