Apple's attempt to protect the iPod Nano from scratches?

It is rumoured that new iPod Nano has raised edges to prevent scratches. There is no official word on this from Apple themselves, but the raised edges have been noted and confirmed by numerous customers and by Apple Genius Bar staff.

In the picture shown the raised edge is clearly visible. The raised edge is not found on any other iPod models including older iPod nanos.

What do we think of this? In all honesty we can't see it being very effective at all. Scratches are often caused by small sharp objects such as keys or coins (objects regularily found in pockets) for example which are not going to be stopped by a slight raised edge. The raised edge will have most effect when the iPod is on a table face down, not something which any of my iPods have been scratched by. Oh well, at least it's a step in the right direction, how about a scratch resistant material next time Apple?
