I'm a happy H4n owner as well. do agree with previous posts, cons, pros. batteries seem to last forever, especially in stamina mode, even if you switch the device on and off frequently. in-built mics sound great with some noise. it's is packed with options and features (effects, pre-amps, compressor, limiter, metronome, tuner, etc.). As disadvantages I find it quite wind sensitive and not very good for recording subtle, quiet, precise sounds on lower gain levels when using external mics. Other than that, I think it's the recorder in this price range or maybe even higher if you consider all features.
for more information on recorders, prices, features available out there check following sites:http://transom.org/tools/recording_interviewing/200703_recorder_reviews/http://corporatetalkradio.com/pdr.html
I also highly advise reading Aaron Ximm's web site for excellent, in-depth advice and great thoughts about choosing recorders / other field recording gear, and field recording in general:http://quietamerican.org/links.html
hope this helps,
