Maybe I'm just not enough of a 'power user,' but I've been using Zsh since 2008 ~ 2009, and I rarely encounter the command-correction. The couple of times I've had it invoked were times where it correctly fixed a typo.
It does fix typos for me too, but most of the time asks weird things like, I typed 'aptitude' did I mean '.aptitude'? It loves misinterpreting some of my commands as dotfiles. Huh?
Then again I have a knack for unintentionally breaking computers, so maybe I've done something in env or rc that's messed it up...
