I've been using Linux in some form for 15 years. Like you, it's been some pre-packaged usable out-of-the-box distro (Xubuntu, Crunchbang, Mint). I've never once compiled a kernel, as I never had to, or saw the need, and it doesn't seem like fun (neither would fixing the compile errors the inevitably come up when I try to compile anything from C/C++). I've never had audio problems that everyone else seems to have, and I don't get the uproar over systemd.
It all seems to work for me. Am I too much of a Linux noob to appreciate these problems?
