With the music on a CF card...it won't matter if it's playing or not...there are no moving parts. I know the whole..unless the hard drive is active thing...I can tell you from experience that that is total BS. I've had hard drives damaged from falls of less than 3'.
Regardless...IF your HD isn't working any longer...you can cheaply replace it with an iFlash card and a CF card.
D...I dropped that iPod 4 times one after another. One before filming, and three filming. I fully believe you can throw this thing in the air while playing and it will land, and keep playing! LOL
I believe it will work great with flash memory. No heads to crap out. Did not notice that the test was with a flash in it rather than a hard drive.
No the screens...sigh.
