Rupert tries out an eye-tracking laptop and we ask whether the mouse could be on its last legs.

And the ash cloud and snow caused chaos last winter, but it lead to the evolution of Twitter being used for customer service. Are companies learning how to use this medium properly to keep people on the go, on the go?
