Well, as I said before, "But it's kind of new and I don't have hours and hours to probe around the net for other juicy info on it."
My tendency lately is to learn only whatever I need to learn to do what I want to do when I want to do it.
So it may take years for me to know it as thoroughly as "the back of my hand." For now, I'm eminently satisfied with it, and impressed with the reviews. The onboard manual seems to be OK, but (pardon a lifelong habit) I have a hard time scrolling up and down a PDF to look up stuff --I prefer to flip through actual paper pages to learn stuff. (I may print out the whole thing and put it in a three ring binder, like I did with the camera.)
My comment in a previous post about the tone quality is moot. You can vary that.
Sooooo, conclusion: I'd go ahead and get it. I have the 821, as mentioned, but the 822 and 823 have even more capabilities --like having broadcast radio reception, among other things.
I got got mine through Radio Shack, but it's a couple of bucks cheaper through Amazon, I saw from your link. No matter, I needed it right away. I brought it home, stuck a battery in it, and started recording and playing back right away.
I do like the standard extendable USB plug --real handy. It sounds like no big deal, but it is a real convenience, I found after dinking around with it on the laptop. It seems as if they actually put some thought (or consumer research) into it to make it as user-friendly (even given its complex capabilities) as possible. <snark> As opposed to things like, say, Windows 7. </snark>
I see that they have available some kind of sooper-dooper external microphone for it, but I don't need it and apparently, with the 1/8" jacking for that and earphones, you can use any standard set of 'phones and mics.
That was one thing that ticked me off about the microcassette recorder I already had: the phone and mic jacks as well as the power jack were all sort of proprietary. Screw that.
It has a tiny lanyard loop hole in it which I may use, but it doesn't come with a lanyard and I may have to jin something up for that. I hate dropping expensive equipment.
All in all, I'm real happy with it.
