I have one as well and will be testing it out at Delfest this weekend. Should be a few other rigs there, so hopefully some comps will come out of it. I have used it once already and so far it looks like a promising compact recorder.
Things I don't like - recording level dial can't be "locked", no overall margin indicator (it refreshes every 5 seconds or so), level meters are OK but not great, recording dial is sensitive (you have to be gentle or you'll really hear the adjustments - not noise, but drastic level changes), no digital input.
Things I like - 7+ hrs recording on a single set of alkaline AA's, sound (need some comps vs. known references), size (slightly larger than the R09HR), location of the line input doesn't interfere with level adjustment (unlike the R09HR), doesn't seem to have the "clip before peak overload" problem exhibited by the R09HR (needs more testing to confirm).
