Was talking to an older lady the other day. Very non-tech. Only uses an iPhone and an Apple watch. No laptop or tablet/iPad. Gets a surprisingly large quantity of things done via her phone. My phone is an Android. She shared 2 things her iPhone can do that I don't think my phone (OnePlus 7 pro) and watch (Amazfit T-Rex 2) combination can do: - she can always find out where she parked her car - her watch buzzes to war…
You can do almost anything from it that doesn't require a larger screen or a keyboard, and the kinds of activities the larger screen enables tend to mostly just waste your time. Take a typical 2007 "dumb" phone - the watch screen is roughly that size.
It becomes awkward when you need to find something on the web (you can't even access the browser directly, you need to ask Siri and work with a popup), but I was mildly successful following a recipe when cooking. It's plain better than a phone at many other common tasks (following directions, checking the weather, paying for stuff, telling time, etc).
The biggest impact it had is that I no longer feel compelled to reach for my phone in most situations. It's not just that it saves 5-10 seconds here and there: the context switch is brief enough that I can remain focused on whatever I was doing.
(inb4 just turn off notifications, yes I am already very picky about what is allowed to distract me.)
