It just hit me and I am punting on it! And believe me or not, it was not the splashes of colour in the apple invite, this was an afterthought verifying my thinking. It was all those black, aluminum and metal mock ups. And then it downed on me. iMacs circa early 2000. Apple aiming for wide adoption. A nano just released with many colours where Steve said "we finally got it right" in terms of colouring aluminum. You put all these together and you have a brand new colourful tablet!!! Of course I could be wrong. But I think I am probably the first to say it, and I am willing to take a punt. You heard it hear first.
