On the issue of the OSD, while it might vary for you, I tend to use mine a lot. I'm picky and rather particular about having my audio always set up just right and sometimes it requires a few little tweaks. The thing I mainly use it for though is to adjust the volume levels. Even after tweaking the offsets most of my sources tend to vary wildly with what level they need to be at to be considered reasonable. Thus I can change the volume to the proper area easily and then know approximately what I'm getting before I switch inputs. Same thing when I'm watching TV late at night once my girlfriend has gone to bed.

The reason I use the OSD for such a simple thing is because, as cool as it looks the blue display is nearly impossible to read unless you're very close to it. At a distance of 8 feet I typically have to lean forward a bit, squint slightly, and make some informed guesses to tell what it's trying to display.

I'd still love it without the OSD, but I'd probably complain a little bit more often.
