As Apple bloggers anxiously try to be positive about Apple's Face ID, a poll suggests potential customers may actually be repelled by the face-scanning technology.

20 per cent of respondents in a poll of over 2,000 Britons said they were less likely to upgrade to an iPhone X because of concerns with Apple's new face recognition. 61 per cent of these cite security concerns. Only 8 per cent are more likely to switch to the iPhone X because of the face recognition.
