iPod embedded in PowerBook

Engadget points to this pic of an iPod built into what I suppose would be some sort of PowerBook.

The picture is from some patents filed a while back by Apple. I doubt this is on any sort of agenda now, as the second picture in Engadget's post features what looks to be a first generation iMac with an iPod-embedded port.

Still, enjoyable "what could have been" patent pr0n, I suppose. Check it out.
