We love to praise linux constantly and tell everyone to change to it (they should) but what are your biggest annoyances ?
Mine would be, installing software (made even more complex by flatpaks being added, among the 5 other ways there already were to install software) and probably wifi power management issues.
I think things are getting better. I’m not going to lie and tell you that it’s no longer a problem, but I think you can do a lot more with a little patience. I know there’s a lot of different implementations, so you might need to experiment as well. Good luck!
