You knew you could use an iPod as an external hard drive, didn't you? (For instructions, look here.) Many people do it, and it's why references to iPods are showing up in articles about electronic discovery. Here's an example:
Whether doing e-discovery in-house or outsourcing, lawyers should know how their clients' documents are preserved, and for how long. Data might be stored on back-up tapes, individual hard drives, flash drives, CDs and other portable media, home computers, cell phones, voice mail, BlackBerrys and even iPods.
The quote is from "Piecing Together EDD's In-House vs. Outsource Puzzle," one of a collection of articles in American Lawyer's "E-Discovery Trends of 2006." All are recommended, even if not as interesting as your iPod's "Most Played" playlist.
