Question: There are so many reviews spread around the web about the Zoom H4N, some of them praise this recorder, other say some things about bad preamps, hissy mics etc...

Who has had experiences with this device? Would you recommend it? How are the internal mics? I am thinking about going out into the woods to record ambient sounds. 
I also like the multi-track feature and would like to use external mics, too.

Answer: 
I love my Zoom H4n, but be VERY AWARE that the 1/4inch "line level" inputs that they advertise are actually -10db High impedance guitar level inputs, not +4db low impedance professional line inputs. I got caught on that one when I tried to hook up my Sound Devices MM1 external preamp to clean up the mic inputs and there was a severe level/impedance mismatch. Was quite pissed when I discovered that because they are not too forthcoming with that fact in their advertising :(
Interesting questions - I'm currently considering selling my Fostex FR2 LE and buying a H4N; the Fostex just isn't convenient enough for me, its too bulky! I love it, but it spends most of its life sat on the shelf, I need something more handheld.
