Mobile phones have been hitting the mainstream news over the past few days. There was Channel 4’s report about data on second-hand phones not being properly deleted before the handsets were re-sold, there was the latest round of the Smart UK Project and there was Tim Muffett’s story about the mobile-enabled high street on BBC Breakfast this morning.

Cisco’s Visual Networking Index report, which forecasts mobile data traffic for the next four years, anticipates an almost 11-fold increase in global mobile data from 2013 to 2018.

A total of 190 exabytes of data (190 billion gigabytes) is expected to be consumed on mobile devices in 2018; that’s the equivalent of every person on earth streaming a YouTube video clip every day.

This week's podcast starts with Lenovo's purchase of the Motorola Mobility smartphone business. Was it a good deal for everyone?
