As of about a week and a half ago, I moved from a 2020 SE to a Nokia 8110 4G "Bananaphone" (the name totally fits) for my primary cellular device. I still have the SE because I've not found replacements for a few key things yet, but it's almost entirely shut off now. Amusingly, AT&T is shipping me a free Flip IV, because my Nokia isn't listed on the "We know it will work with the 3G networks turned down" device list. The tech support guy was quite amused, as was I, so I'll have a legitimate flip phone here in a day or two as well as the bananaphone.
Perks of the bright yellow "What on earth is that?" - it opens up conversations about why I'm moving off Apple.
The lack of KaiOS Signal is a problem, though I've seen some work towards it - perhaps this will drive more development towards the not-Apple, not-Android ecosystems.
I considered a Pixel with GrapheneOS, but Google's hardware reliability lately has left an awful lot to be desired, and I'm just tired of the smartphone concept anyway.
I've been playing casually with a PineBook Pro for the past year or so, and I'm getting that into duty to replace my MacBook Pro for in-house laptop use. There's a new firmware that makes the trackpad actually good, not the laggy, clunky, borderline usable thing that it shipped with, so that's been nice. I simply don't use that much computing power in the evenings, and the PBP accomplishes most of what I want. Unfortunately, again, it doesn't have things like Signal as "easy to install" options (AArch64 is worse than ARMv7/AArch32), so I should throw some time at that as well.
My office, which has a M1 Mac Mini I've done quite a bit of testing and work on, is going to suffer through going to a small ARM box as well - I'm going to put an ODroid N2+ in there, and see how it works. I'll have to drop back from the LG 5k to a 1440p display, as the ODroid can't drive the 5k, but... eh, whatever. Again, I just don't use the computers for an awful lot. I will lose some functionality with regards to video editing, but I simply don't do much of it, and I do have an x86 Windows/Linux PC in the house I can do that on if I need.
The one thing I've not found a great solution for yet is the iPad. I use it for PDF reading, for web browsing, etc. It's probably safe to use in that style, if I strip accounts off, but... even then, I'd like to get rid of it if I can find an alternative. That's going to be a longer project. I'm very interested in the PineNote announcement, as it would make a great PDF reader in theory, but see "a lot of development to make it work." They don't even promise it will run the display when shipped...
As for paying for things, I've got contactless credit cards that can largely replace Apple Pay for "wave something and go," I just have to separate them from the stack of cards first. Not a big deal.
There's a definite loss of function here, but I'm unwilling to state strongly that I'm opposed to all this, and then continue using Apple products as before.
And I've been looking to get away from the tech ecosystems for a while, so this is just a good kicker for me to do it.
I'll probably keep the 2015 MacBook Pro as a "I do still have some value to an Apple device, Apple having been part of my life for nearly 20 years now," but I'm going to strip stuff off and leave it mostly in archive mode.
