There have been a few comments here regarding the R-09's build quality... not the most confidence-inspiring, even without considering the flimsy battery door. Well, the other week I had a little accident with my unit. I was on the road, had to get my miles in (training for half marathon coming up in 2 weeks), had just recorded a gig the night before and I *really* wanted to listen to it so I brought my R-09 to the local gym. (Being on the road without my lappy I didn't have the opportunity to offload the SD card or somehow transfer it to my iPod.) I set it carefully on the treadmill shelf (not in a protective case), headphone cord was long enough, got into my run with some good tunes... everything was fine for 50 minutes but then... somehow while wiping my face with my towel I managed to knock the R-09 off the shelf. It bounced off the moving surface of the treadmill (a drop of about 3 ft) then got propelled backwards, slamming into a wall about 2 feet behind me. F%$k!!
Well good ending to the story, the unit shut itself off but when I powered up again everything seemed fine with controls and playback. I have subsequently used it for recording and all is well.
I realize that the somewhat "soft" surfaces of a treadmill and drywall are nothing like concrete or tile, I know an encounter with a hard surface would be no match... I just throw this out there FWIW.
(And please, don't -T me for not taking care of my stuff, I was dying to listen to the gig I'd just recorded and after all everything *had* been going just fine on the treadmill for almost an hour)
