The cheapest iPhone X (64GB) will cost you $999 (£999, AU$1,579). Expect to spend less on the S9, and you get two price points to choose from. Prices vary from carrier to carrier, starting at $720 (£739, AU$1,199) for the S9 and $840 (£869, AU$1,349). Those are also 64GB models, but -- unlike iPhones -- they can be easily and massively expanded with the addition of cheap MicroSD cards.
