Even in simple scripts I found arrays to be very helpful once I let go of the "POSIX sh mindset" and was used to it. The way word-splitting and $IFS works is basically like an "implicit array", as is $@, $1, etc. (actually in zsh $@ is an array: $1, $@[1], $*[1], and $argv[1] are all the same), so everyone already uses arrays. It replaces a lot of uses of cut and "awk '{print $2}" for starters.
