And that is relevant to today's Apple how?
The higher prices are due to Brexit (and other factors) causing the value of the pound to drop. So that's not Apple's fault.
Wrong. Their pattern of price increase has nothing to do with Brexit, Ireland, etc., as it has been steadily the case for years since iPhone 3G, with a rather pleasant exception of iPhone SE & some iPads, before they started forcing people to buy higher than needed storage models. At the same time Apple are busy trying to corner their suppliers into dropping the price of the components, thus trying to maintain their hyper-high margins. This is greed, my friend. Accidentally, I bought my first iPhone (3G) in Brighton for £382 from O2, as they were "exclusive" back then. From then on, the prices were climbing higher & higher.
