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.

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.

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

I’m using Feeder currently, but I am looking into setting up FreshRSS or Miniflux for easier cross-device use.
