How will five of the most popular tablets stand up to a pounding from a herd of cows as well as a real game of angry birds? Back in ... (more)the studio, Jon Bentley is looking at the world of digital assistants – smartphone software that claims to be able to organise our lives. Do they really work, and can Google’s Now and Samsung’s S-Voice really challenge Siri, used by Apple’s iPhone? In his first European trip of the season, Jason is the Austrian mountains to see what happens when you mix a tank, a wheelchair and a pile of snow. The result is an extraordinary form of transport! Meanwhile, on the other side of the Alps in Italy, Ortis joins newly crowned Italian barista champion Giacomo Vannelli to test coffee machines.

She also reveals how these satellites in the sky could soon be doing something much more than just helping people to get from A to B.
