"Sounds more mysterious, iPhone X."
My favorite color is black wearing black pants, socks, and shoes every day. But always picking black or dark colors every time is as predictable as the color the goth crowd, Darth Vader, and The Undertaker wears. Here comes the MiB! Space gray X is still nice but it's not my thing this round.
Space gray X = jet black 7, sp gray 8
Silver X = throwback option
Silver X is like every iPod released from 2001-2006 with the classic white fronts and 2007-2009 iPhones when white fronts weren't an option yet. Paying homage to 2001-2009. The 2000's Apple when they were at their peak in coolness and design.
The sole purpose of the X's creation and call it "Ten" was to honor this phone...
My choice was clear back in September 12, 2017. Might as well get the color with the silver metal around it that looks and tries to honor the original.

Rich DeMuro showed it the best.
