I picked up an Apple iPod this week. A very cool little toy; it’s basically an MP3/AIFF/WAV player wrapped around a 5GB Firewire hard drive, smaller than a pack of cigarettes. On top of being the coolest thing since sliced bread, it also has enough output (or the right impedance) to drive an unmodified Garmin audio panel to very comfortable volume levels. Sounds very nice in Bose X headsets, by the way. (There, it was a little bit aviation-related.)
Plus, if your laptop disk crashes while you’re flying, you can boot off of the thing (it’s a Firewire hard drive, after all.) That’s kind of aviation-related too.
Holds some 80+ hours of 128Kbps MP3s, prorated appropriately for higher bit rates. Battery purports to be good for ten hours or so, though I’ve never run it all the way down. Should definitely outlast the gas tanks in a Cirrus (there, I’m keeping it on topic.)
