This week we chat about the reasons for Twitter posting a net loss of $645m, the implications of these rather dismal financial results and what might be done to turn the social network into profit. Paul Cooper has a warning to anyone who has ever sold a mobile phone secondhand,  perhaps wrongly thinking their data has been erased. Plus the new Samsung Galaxy S5, the unexplained removal of apps from iTunes and change at the top as a new CEO of Microsoft is announced.
