When we first saw the latest iPod shuffle, our immediate thought was "make it any smaller and you'll have to build it into the headphones somehow." We doubt anyone was listening, but that's pretty much exactly what has happened with the Sony Walkman W260 ($60-$80). Designed with active users in mind, the W260 is rinsable, wearable, and water-resistant, and offers features like quick charging, a black or white casing, and either 2GB or 4GB of storage.
Step one: Make the first fashionable Bluetooth headset. Step two: Make portable Bluetooth speakers more than just geeky add-ons. Step three: Use that experience to make the first lifestyle gadget people will actually want to wear. The Jawbone Up ($TBA) is a small, sensor-loaded wristband that you're expected to wear more or less all the time, so it can track your movements, sleep habits, and, via a companion app, nutrition, helping you fend off heart disease, diabetes, and other lifestyle-related issues just by having it on.
Attention all lifestreamers: Ever get tired of holding up a camera all day, or worse yet, wearing some sort of incredibly dorky, Wi-Fi enabled video helmet? ZionEyez Video Recording Glasses ($150) can fix all of that. These semi-stylish shades feature an integrated 720p video camera, Bluetooth to instantly transfer the stream to your iPhone or Android device for uploading, and 8GB of flash memory in case you need to off-load your recordings later, secret agent-style. As a bonus, they come with clear and shaded removable lenses, so you don't have to worry about looking suspicious with your sunglasses on after sundown.
