WiFi public space

This is great! an exhibition of 'WiFi Furniture' in the British Library: furniture specifically designed for use when using wireless equipment. I particularly like the Lean Back-- it's very comfortable. I could imagine something like this being incorporated into the design of a public space. Wouldn't it be great if there were elements designed to work with your body-- e.g. something to lean against when making a mobile phone call? or rest your bag on while taking down a phone number? It would be fascinating to do an urban design project to allow people to more easily use these kinds of technology while in public space. What would the space look like? would it be all ledges and walls for leaning against? alternatives to benches and chairs? public desks? with power sockets?
One of the key criteria would have to be ergonomics and how the body moves and responds to the space and the architecture. Often overlooked in urban space design. And architecture.
