As I mentioned downthread, surprisingly little stuff breaks by accident nowadays on Arch (on my desktop, zero breakage in the last year with a fairly complex stack; on one server machine I had one strange interaction between a language package manager and pacman that ended up being my fault). The "slow but dependable" solution ends up breaking as soon as software becomes too complex for maintainers to be able to backport security fixes onto old versions, so they just ship the latest version of those packages, negating the dependability aspect (like Debian's treatment of Firefox and Chromium).
