@prettygood i use zsh and touch computers pretty regularly.. not for a living though :3
about the only thing i'm uppity about with it is having a right prompt, most everything else i admit can be done in bash... it's just really nice having the time/date there, say compiling things or updating and being able to see when they finished
if i did it for a living, i might put repo status stuff there, all tucked out of the way ^^
