We're at Mediatech Africa 2017 for this edition of the TalkCentral podcast. Show regulars Duncan McLeod and Regardt van der Berg are joined by "Mr Mediatech" Simon Robinson to chat about the event, as well as all the week's biggest technology news. On the podcast this week, the US$20 4G phone, and why it's potentially a very big deal. Also this week, Vodacom's impressive first-quarter financial results and Openserve slashes wholesale ADSL and fibre prices. Plus, are you brave enough to be one of the first to hitch a ride on Elon Musk's Falcon Heavy? Regardt's pick this week is Mozilla's Project Common Voice, while Simon has again chosen BlackTrax (on display at Mediatech) and Duncan's pick is Justice Malala's Burning Platform podcast on CliffCentral. Stream or download the podcast to find out who's been chosen as winner and loser of the week.
