    Use accelerometers to detect when the device is in free fall and shut down the hard drive before it comes to a sudden stop and gets damaged. This paper is suggesting that you only have to measure acceleration in 2 axes to detect that the device is falling, not 3, as you might expect.

    I think the Sony HD5 already has this; can anyone confirm?

    I think the HD3 uses a similar device called a "Flux capacitor" :)

    Didn't want to start a new thread, so check out Sony's new 5gb CompactFlash Vault, simple called CompactVault

    Miniture/or small-ish Microdrive DAPs in future, or stack 2 together for a pretty small 10gb DAP?
