I also use the R09HR, for field recordings (either with the internal mics or 
with a variety of external mics) in conjunction with video recorded with my 
It's small, and can record in 24-bit WAV format for optimal quality (or MP3 if 
you're desperate for space). It also timestamps each recording file, which is 
essential for my work.
Earlier I used a Zoom H4 and the R09HR is much better for me. The newer H4N 
might be an option, although it is larger than the R09HR.

The H4 had issues with internal hum from the power supply affecting recordings, 
which some people hacked with hardware mods, but I was able to avoid it by 
using an external power supply (driven by a Canon BP-511A battery!). If I 
recall correctly the H2 had some issues with noise on external microphone 
input, but my info is probably out of date.

The H4 could be connected via USB to act as an external mic/XLR IO box for your 
computer, but I don't need that. I just pop the SDHC card out of the bottom of 
the R09HR and transfer the files to the computer that way.

I do wish I had a good wind-break muffle for the R09HR, but using external mics 
avoids that issue.

The H2 wasn't new in late 2008 when I got my R09HR, so I'm not sure where you 
got that from!
