Always On

Mobile phones, laptops and tablet computers give us the opportunity to be constantly deluged by information wherever we are in the world.

And if we have one of these devices and don't turn it off then we can be reached, wherever we are.

But - as Dominic Arkwright asks - is this development in our lives a good thing?

With Financial Times Slow Lane columnist Harry Eyres and Guardian digital media correspondent Jemima Kiss.

Plus the best selling author William Powers who's written a guide book on how to live wisely and happily in a connected world.

Producer Paul Dodgson

First broadcast on BBC Radio 4 in June 2011.
