I am teaching myself how to scull on the Charles river and I fell in twice this morning (I bought my 6th gen Nano last nite and had it clipped to my shirt.) Each time I fell in, I was totally submerged for 20-30 seconds. The nano kept playing without a hitch and is still just fine.
It is not advertised to be waterproof, but it clearly is. Bravo Apple.
