Not so sure . The X price point and moving away from touchid is not for everyone . The iPhone 8 is a very nice unit
Just can't see people deciding to get a X over the 8 all the sudden.... it's £300 more..... that is a very large amount .
Face ID works better than touch. And that £300 is about £4 extra on your contract. People don’t look at the over all cost they see £65, £69, or £72 a month for example.
