We have something for everyone in this week's podcast. There's bad news as Samba Mobile closes, bad news as Apple and Samsung suffer product faults... and bad news as wearable devices are criticised for the poor user experience they offer.

Yet there's plenty of good news as well, including the launch of a new UK mobile payment service.

This year's Mobile World Congress was notable for the number of product launches by handset manufacturers. To get a better understanding of smartphone manufacturing, we spoke to Johan Lodenius of semiconductor company MediaTek.

He gave us a simple overview of how 'fabless' manufacturing works, discussed developments in smartphones and wearable devices, contemplated the end of the PC era and talked about the importance of driving costs down.

Dr Kevin Curran, Reader in Computer Science at the University of Ulster, joined us during Mobile World Congress to offer his well-informed opinion about trends in mobile technology.

We talked about a wide range of topics, including battery life, disposable tablets, wearables, m-health, 4G fragmentation, connected furniture, M2M security, the rise of video and the IEEE.

James Rosewell and Mark Bridge report from Mobile World Congress 2014 in Barcelona.
