hmm ?  Uh , well we can use wood.  I don't know why we'd want to. Um and also we should note that if we want an iPod-style wheel button , it's gonna require a m qu slightly more expensive chip. We can't use the minimal chip , we need the next higher grade , which is called regular. I don't think it's much more expensive , but it is more expensive. So that's what I've got on design.
'S good.
Um , can I do next ? 'Cause I have to say something about the material
Hmm.
