Summer's in full swing, and for many that means hitting the open road on a family vacation or freewheeling road trip. If you plan on putting the pedal to the metal, don't forget to pack some gear in your travel bag. We pulled together five gadgets that will help you get where you're going and have fun while you're at it. The iPhone can get you traffic info as well as play tunes, while the TomTom will direct you to your destination and DS Lite keeps your passengers happy. And don 't forget to take pictures: The SD850 takes beautiful pictures, while the waterproof Xacti can shoot video by land or sea. Now gas up and get going!
