I can tell you what I don't like about linux, the numerous updates to software. I can not stand how many updates there are to software, not only every year, but just down to the day. I don't even try to keep my software on the bleeding edge, but damn it, I want to keep the version that worked for me. With many distros I've used: notably, gentoo, ubuntu; I've noticed that updates tend to break my software installs. yes, I understand dependency hell, but that's not what I am talking. Case in point, I've been writing music with lmms since 0.4.13 and damn it, I have to keep 0.4.13 plus the current versions of dependencies. if I don't do this, I get terrible noise in my songs, and some of the instruments straight up do not work. This is not what I consider something productive. It's infurating. LMMS 0.4.13 is extremely old, but there should not be any reason that newer versions can't handle files that I wrote with the old versions. They should be compatible.
This is why linux is not used productively. There is too much change. There is too much incapatability within the software its self. It's ridiculous to expect anyone to accept this.
What problems do you have with linux?
