Ah-HA. I didn't know the Rockbox software didn't work on the FM model, which I have. I thought I was doing something wrong because I couldn't get it to work.
I can't speak for the battery life yet, since I haven't used it except to move music on to it. I've used it for at least 8 hours this way without the charger, but maybe it's leaching power off the USB cable.
It's totally silent. The only thing I've noticed when it's on is a slight gyroscope effect when I hold it, a sensation of something moving that's unlike a vibration.
It does take a second or two to boot, and loading a 20 song playlist also takes about a second. I tried to load the Rockbox software because it claims to eliminate the playlist load delay. It's not a huge deal, though.
It does not have a microphone jack, just a line in. I don't really care, since if I'm going to record something, I'm going to do it from my stereo, or by converting a CD. That's why I didn't comment on the record-from-radio feature, it just doesn't interest me.
It does act as a portable hard disk, which doesn't really matter to me either, but could be useful to some people. If there was some way to hook it to my digital camera, I'd be really psyched, since smartmedia cards are expensive, and I'd use it to store photos in trips. However, while they are both slave USB devices, and cannot talk to each other. I suppose I could use it that way if I borrowed someone else's computer.
If Android's Archos Jukebox could run the Rockbox software, maybe it was the non-FM model, and perhaps they changed the batteries? As I said, a review I saw of the Recorder claimed it took AA's, not an internal lithium-ion battery. I know that the new GBA-SP has a lithium ion battery, which gives it about 60% more battery life than a regular GBA with two AA's.
All in all, though, I'd rather have 6 hours of battery life and easily replaceable AA's than 10 hours and a hard/expensive to replace specialized battery. I've got several extra NiMH AA's.
It's possible the whining problem could have been specific to Android's copy. Hard drives just don't whine these days, as a rule. I assume it depends on the bearings.
