If you type the say command into Terminal on a Mac and have it say "iPhone X" or "Mac OS X" it will pronounce it correctly (Ten instead of X). Doesn't relate much to the argument, other than being a neat easter egg.
They're changing the product positioning in the line so that the most popular model is now the "normal" one, and premium models are a step up from that. Honestly I like it better than giving the high end model the default branding with a worse model below it that most people will actually buy.
