I’ve been using Runbox for a couple of years and agree the web interface is lacking. There were also multiple significant server outages last year, but it has been much more reliable this year. As long as you don’t use the webmail often, Runbox is a good affordable email provider and is great for families due to the low cost of sub accounts (additional users).

Liftoff for now. It's the least buggy Android client I have come across. I definitely prefer Memmy on iOS though.

They are not ready for regular use yet. Performance is poor and battery life is bad. It's fun to play with my Pinephone and watch the software slowly improve, but there is no way I could use it as my primary phone.

I hope they bring the Fairphone 5 to the US in a reasonable amount of time, because the 4 is just too old for the price being charged.

Kind of. There is the PinePhone and Librem 5 that both run full Linux. I have a Pinephone. Unfortunately, the hardware is underpowered and the software is not ready to replace iOS or Android. The battery is also not good. The standby has improved a lot, so it can last a day of limited use, but the battery drains very quickly when the device is actively being used. It's definitely fun to play around with, and it even has the convergence feature Microsoft tried to do with Windows Phone. The UI changes to regular desktop Linux when plugging the phone into a monitor and connecting a keyboard and mouse. But again, the hardware really limits what can be done.

In short, Linux phones are a thing, but not reliable enough to be the only phone a person has.

Slide is open source.

Good old reliable RSS. You get exactly the sources you want and without an algorithm trying to influence what you see.

That's one of the most significant reasons I stopped using YouTube Music.

Good overall recommendations, but it's worth noting that Obsidian is not FOSS.

I haven't had any problems with btrfs. There have only been a couple of cases where I used the rollback functionality and it worked as expected. I have also been using a Synology NAS with the btrfs file system for several years without any problems.

openSUSE Tumbleweed because it is the most reliable rolling release distribution I have used. I love the automatic btrfs snapshots and wish other distributions would have them setup out of the box.
