Using a low-impedance pro mic with a high-impedance 1/8" jack on a PDA or MP3 player/recorder?

    Please help. I'm stumped.

    What mic(s) should I consider for recording a conference / event? Omni
    or condenser? Or is it just plain foolish to believe using a
    low-impedance pro mic with a high-impedance 1/8" input jack on a PDA or
    MP3 player/recorder?

    Also, can anyone suggest good articles or sites containing round-up
    reviews of PDAs and/or MP3 players / recorders for podcasting? I'd
    prefer a PDA, because I could use it for things other than podcasting
    (gaming, pocket excel / word, WiFi, etc).

    I am worried about PDAs and battery life.

    Some of those MP3 players that claim a battery life of 14 hours
    actually mean 14 hours of MP3 playback, and not recording - one I had
    would indeed last at least 9 hours for MP3 playback, but died after
    ~1.5 hours of voice recording.

    I would buy a Marantz, but don't have an extra $600 to spare. This is
    for a non-profit event, and I don't know anyone who will rent me a
    Marantz + pro mics in my area.

    I could use my laptop, but laptops seem to introduce too much noise,
    and they also have a tendency to freeze at inopportune moments. Hope
    the same isn't true of Palm or Pocket PC / Windows Mobile PDAs...

    Omni is a mic pattern. Condenser is a type of microphone.
    makes sense. I record some conferences on an AC powered laptop and back that
    up with a dedicated audio CD recorder in case one burps.
    where are you?
    hope not either. :)

    Right. Sorry for butchering terms. Still learning.

    Mic choices seem to be:

    1) Omni or directional

    2) Dynamic or condenser

    3) Handheld or lavalier (lavalier seems to be universally loathed in
    pro audio with a few exceptions)

    4) Inexpensive or take out a second mortgage... :)

    5) Mono or stereo - why stereo for voice recording where I don't
    require "ambience" like a roving BBC or NPR reporter?
    Doesn't the laptop not introduce hiss and hum? I know these can be
    removed later with a good filter / editing package (Audacity is
    probably the only thing in-budget for me though, being free, as in free

    Or is this largely a concern when recording live music?

    It's often useful to have two mics and a stereo recording. One mic is on the
    podium for the main speaker, one out in the audience for questions.
    A laptop with an outboard microphone preamp will make a clean, quiet
