Its quality is pretty much as good as the rest of the other Nomads (very decent), although it is designed to be pretty much bare bones (no eq adjustments, treble, bass).
It should be fine for what you want, although it's not really expandable.
I had one to test about a week or two ago....I was intent on buying it, but then I thought I might wait for the next model to see if they have more features.
Its use as a USB pen drive is nice (I'd probably use that quite a bit), but it is significantly slower than regular USB pen drives because of its format and MP3 capability.
