The iMac is going to be an unobtrusive yet elegant, white plastic object, sitting quietly on your desk, probably with a very simple form factor (Sphere, Cube, Cylinder), possibly with some "legs" for support. It will come with a fully adjustable screen which can be hooked off and used as a tablet, communicating wirelessly through Airport. Obviously they will be delivered with the new wireless keyboard and mouse and the new bluetooth graphics pen, which can be used on any surface as though you always had a graphic tablet with you. The iMac will be slot loading and feature the new dynamic ornamental appearance to provide feedback about the wireless components, as will the tablet/screen. The tablet screen can be also hooked up to the iPod's dock connector. You can combine these and an add-on battery pack for true mobility.
