Slight tangent - In my view, forward/next wizard style forms are used much too much. Quite often it's a metaphor that suits the developer more than the user - to ease validation, data manipulation, etc. Generally a user just wants to do some "stuff" (usually data entry) and then trigger a primary action "submit, commit, buy, sell, order". I've found a lot of sites lock the user into the "next/back" for all the "stuff" pieces when another metaphor would work a lot better.
