The drawing is crazy to me. Although it would be cool if, keeping the trackpad (and perhaps even dropping the button?), the trackpad had the clickwheel drawn on it, and had enhanced functionality (à la iScroll) that used the image of the clickwheel. 🙂
But that aside, lots of notebooks used to (maybe still do?) have the ability to play CDs without fully waking up / opening. If the iBook gained the ability to use the full iTunes library clamshell, I'd think that could be fun. It's a whole different value equation now than when the CD feature bowed, because back then few, if any, people had their entire collection of music ripped on their HD. Now..... 😀
