Like all good lists, there are 10 of these but my favorites are:

• Train Doctors to Save Lives: iPods can double interns’ ability to identify heart sounds
• Bring Criminals to Justice: using iPods to hold copies of wiretap transmissions in a large drug-conspiracy case.
• Record Flight data: iPods as flight data recorders in light aircraft.
• Flashlight:  For about $13, you can purchase Griffin’s iBeam, an attachment that will quickly turn your iPod into a combo flashlight and laser pointer.
