That is a really really nice concept (for the OP). Reminds me of something of Men In Black or Star Gate, possibly Star Trek. It's a really nice concept idea. Good work!
I can never create anything like that!
The way I always saw the perfect iPod + phone controls would be RAZR-esque metal pad for buttons, maybe minus the rubber edges for the buttons, this would then be overlaid with the old fashioned 3G touch wheels which would be flexible so that you could still see the numbers/letters buttons underneath and push/click them when needed, otherwise you could just rest your finger on it and scroll just like the old 3G iPods. Probably never work but that's just how I always saw it. Don't ask me what my ideal case design would be though!
