R-09 with its built in mics would make a horrible all in one. I tried the built ins once to record a friend's cover band and the sound was immediately noticeable as way way worse than using an inexpensive mic such as CA-11s. Not even enjoyable to listen to.
If you let Chris Church turn it into a Micsketeer by installing CA-11 card or omni caps, it's a whole different story. Sounds every bit as good for recording loud stuff as using a battery box and external CA-11's and will not distort at ear crushingly loud volumes. For very quiet stuff, you still need externals & a preamp or it will be noisy due to the R-09's preamp.
I gather that the H2 would be a far better choice than the R-09 if you are recording stuff that is not too loud. However for loud stuff, as is well documented here, you will probably have problems with clipping.
Way better than the H2, now for $280 shipped on E-Bay, would be the Olympus LS-10. Several respected taperssection members have recommended it for point & shoot stuff when you only want to carry a small all in one. Others have recommended the Tascam DR-1 which is considerably cheaper ($200 on E-Bay) and also, I think, a lot better than the H2 for recording live concerts.
