The story of HTC's recent fortunes is one of the more bizarre tales in modern technology. What other company releases award-winning flagship after award-winning flagship, only to see revenues and market share drop? For a while, HTC's phones truly stood out in terms of design and build quality (since 2012 there's been the One X, the One M7 and the One M8). The One M9 represents another iterative step forward for HTC, in a product cycle that has (debatably) seen rivals Apple and Samsung make huge leaps forward. But it's not all doom and gloom. Even if the M9 is being mooted as a potential miss, the Vive, its new virtual reality headset, is perhaps the biggest hit of the show. I sat down with the man at the heart of everything HTC does, chief designer Claude Zellweger, to discuss HTC, the company's direction, the M9 and its entry into VR.
