The camera contains color-correction technology, a 2.2-inch display screen and a tether that connects the camera to a computer. You'll need that: Each 39-megapixel image is a whopping 78-MB file!

blue ears Everyone's experienced it: watching some guy talk into space, but then noticing the Bluetooth wireless mike receiver in his ear and realizing he was on his phone. Motorola's gotten rid of the microphone with a new Bluetooth unit, the H5 Miniblue, which plugs into your ear and picks up your speech from the sound within your ear canal. It's said to be crystal clear. The outside is about the size of a quarter and has a rechargeable battery good for 90 minutes of talking. Prices had not been set at press time. Of course, you'll need a Bluetooth-enabled phone, but it can be 30 feet away. www.motorola.com.
