I upgrade my iPhone each year (usually with the top of the line model), but $1829 for an iPhone is steep.
I'm on the fence at the moment, but knowing me I'll succumb closer to the day and buy one.
I'll probably pick up the iPhone X 256Gb Silver. I usually get the black/space grey option as I prefer to have a black front, but now that both models sport a black face I might go for a change. I have not had a white/silver iPhone since my first iPhone 3G all those years ago. I figure if I don't like the colour, I can put it in a case and turn it back to a black iPhone.
