Android. That is all.
I prefer to pick my poison, and I'll eat no apples.
I realize that Android is in its own way a bit of a closed garden, but much more open than some other competition. So I am an Android guy, and I will be until something better comes along.
Devices
I have a Pixel 6 as my phone and a Google Pixel Tablet as my tablet. I also have a few Fire HD8s around because they make great little ZoneMinder monitors and/or just random book readers and they're dirt cheap on sale.
The Pixel 6 is stock and I've never even rooted it. I hadn't used root a ton in the last few years except for adblocking, making backups, etc. I miss having backups, but adblocking is sufficiently done with the Pi-Hole in the house. I do not miss having to do special things in order to update monthly.
My Google Pixel Tablet is pretty new as of this update but it's so far primarily living on my desk on the dock and just keeping itself front-and-center, being useful as a weather portal but also reminding me of its existence.
I still have my Fire HD10 that I de-Amazoned. I never rooted it, but did disable updates so it wouldn't keep enabling Amazon software I don't really need. It's really not a bad device but I replaced it with the Pixel Tablet for a few reasons. It's not the fastest, and the battery life when gaming on it isn't great, but it'll get me a week just hosing around on IRC for a couple of hours in the evening using my Bluetooth keyboard. I'll likely keep it around for a while, but then again, I'm a bit of a device hoarder.
Apps
Android wouldn't be that useful without apps, of which there are 1,639,669,127 and counting in the Play Store. Here are a few I use daily.
Tasker
Tasker automates many things on my phone and in the house from turning the lights on and off for me or tracking me into my own database for history/statistics. It automates many things for me on my phone, you can even view a partial list of such things.
Fair Email
K9 email went through a long period of few updates and I migrated to Fair Email, which is a rather good client and fits my needs well
Flowx
I am a weather nerd and Flowx gives me SO much weather info
RainViewer
Extremely detailed information on upcoming rain and radars
fbreader
Best etext reader, hands down, I've read hundreds of books on fbreader over the years
Dairio
Private diary of notes, reminders, and just "what happened today". I reference it a lot to remind myself when something happened or when is the last time I trimmed the ferret claws
And there are many, many other apps I use - I have tons of apps, maybe I'll think of more to add to this list to highlight.
