You don’t install gmail, you connect a mail client to it or visit it in a web browser.
TIL. We really do live in separate bubbles.
It’s great if you never search for email I guess.
...from 5 accounts with at least a decade of history each, incl. my office e-mail.
But that means any spotlight bug is a mail search bug, and a settings search bug, and a “just launch this app” search bug, etc etc etc.
It also means that any bugs caused by one of these applications end up affecting them all. So if Contacts causes an indexer crash, none of your searches anywhere work any more. It’s a super fragile architecture. They did some work to split some of the plugins into separate processes but somehow it always ends up being insufficient.
At least on macOS there are some commands to blow away your spotlight index when it goes bad. On iOS you’re basically screwed unless you wipe and restore the OS.
These types of things should stand as big massive red flashing warnings with all these locked down systems - as you point out, in certain situations on iOS you’re just stuffed.
If I took over Apple's software engineering, I would tell every engineer "None of you are working on features until a stock OS install has zero error/warning logs. No exceptions. Contribute to fixes or use your vacation time, but nobody touches anything until we get it all fixed. Then once that's done, nobody's allowed to work on features while there are open bugs in their backlog. No exceptions."
This is why Gmail is nicer in many areas.
Why would Gmail be pre-installed on iOS?
The thing I miss most about macOS now that I’ve gone all-in on Linux is actually Apple Mail. It’s just a simple and clean Mail app.
My current choice is Evolution and I’ve had very good luck with it so far. But ultimately the best Mail experience is on my iPhone.
I was using Thunderbird/BetterBird, but now that a Windows client isn’t a requirement for me anymore, I much prefer Evolution. Thunderbird is a notable pain when it comes to an inability to reliably export/import your user profile to other machines. It’s also such a cluttered application and I find the calendar UI to be horrendous. Good luck using a trackpad to scroll through months of the year.
The real reason I'm still using POP3 is that I'm using the mailboxes that are bundled with my domains. One on the registrars announced IMAP support a few days ago. All the others are still on POP3 probably because POP3 servers have been available since forever.
I'm using Thunderbird with POP3 accounts, download on my laptop then remove from the server, daily backups. My phone has K9 (the old one with the UI I like) and I never remove messages from the phone. When I send mail from the phone I bcc myself so I can see the message from my laptop later.
Why? Because I don't like to leave my mail forever on somebody's else server. They can lock me out at any time (it will probably never happen) and my mail is mine.
Would I recommend this to anybody? Of course not.
Is it a problem not to have access to all of my mail when I don't have my laptop with me? It never happened to be a problem and it's always less likely to be a problem because of all the messages that are exchanged outside email and on mobile first platforms, even for work.
