How much cheaper is 7000 series than the grade of stainless Apple used to use? There didn't used to be much difference per kilo, although I know less of it is used and machining stainless comes at a higher cost. It would have been nice to see £50 taken off the cost, but that unfortunately didn't happen. The Apple Watches got a £30 reduction compared to last year though which surprised me.The iPhone X using stainless steel was one of the reasons it justified a premium price point. They have now reverted to using the “cheaper” material, while keeping the same premium price.
