I’ve spent most of the last six months buying a house, so you’ll need to forgive me if I have houses and house metaphors on the brain. I’ve found them helpful while trying to nail down iOS 10.

Imagine iOS 6 as a fundamentally solid house in need of some major remodeling. iOS 7 was largely a cosmetic update, putting on some new siding (or maybe a nice brick façade) and giving all the rooms a nice paint job. iOS 8 with its under-the-hood changes was roughly equivalent to replacing wiring and plumbing—stuff that’s harder to see but makes a big difference in everyday usage. iOS 9 gave an extensive makeover to one particular room (let’s call it “the iPad”) that had been basically fine for a while but wasn’t being used to its fullest potential.

In the context of this overextended metaphor, iOS 10 is best thought of as an effort to redo multiple other rooms in the house, knocking out some figurative walls and removing metaphorical ugly dropped ceilings. For the first time in a while, Apple is making notable changes to the way basic things like the lock screen, the notification center, and Siri look and work.
