I like this. I'm thinking: what if the iMacs shipped with a keyboard like that, basically one with an integrated iPod Touch style device where the numeric keypad usually goes? I suppose the most obvious use would be for programs to delegate some controls onto that touchpad. For instance, sliders for an audio mixing program. The rest of the time it could just be a keypad or collection of shortcuts. Or maybe a good place for notifications/readouts like newsfeeds, tweets, system monitoring, etc. Can anyone think of more innovative uses?
