Apple Mac Tablet in 2007?

There are rumors from Mac Rumors concerning a possible 2007 launch of a Mac Tablet PC with Docking Station. In fact, Smarthouse AU claims that Apple actually has a working prototype Mac Tablet in their labs now!

The target for the Mac tablet will be for home and education markets rather than the enterprise market according to the following quote:

The Mac tablet has been designed to handle third party applications such as home automation software that will allow users to control lighting, audio, entertainment devices and security feeds. It also acts as a full blown PC has wireless linking for a new generation of Wireless Hi Fi speakers that are currently being tested by Apple.

If the rumor is true… what will be the actual tablet be able to do? Will it be a computer that runs specific apps for the home (home automation, home theater, etc…) or will it be a full-fledged computer?
