A  brilliant demo has been released of just how well all of Microsoft's various kit connects-up, links-in and generally gets-on - and gives a sneak peak of how we may be using multiple systems in the not-too-distant-future.

The demo involves a nice chap from nsquared having to solve a door-handle issue on a house he's helping to design/build. Using a  Windows Phone 7 handset, Microsoft tablet, Surface and Kinect he manages to show off the various ways the different tech can be used together.

The demo comes from TechEd Australia 2011 developer keynote, and also highlights the excellent Microsoft partnerships, nsquared being just one, that will no doubt bring much innovation to MS products;  it certainly fires up the imagination.
