I tried it with Audacity on my desk to record my pod-casts and with my Kodak Zi8.  Both pretty weak.  I recorded someone talking with the zi8 as a test.  First with the sony mic and then without it.  First with mic sensitivity levels at normal and then again at max.  The Sony produced much more hiss and was nowhere near the sensitivity of the Zi8's internal mic.  The zi8's mic picked up so much more ambient noise and the voices were so much more robust.  Was really surprised to hear all the positive reviews with the Zi8.
