You are being hopelessly dogmatic on this point. I'm not sure it's worth belabouring.

  I'm coming off that way, and I apologise. I wasn't clear. I believe the original article was mostly discussing these factors within the confines of web based applications, which is what my comments here have assumed. Obviously their are exceptions to the rule, and a true undo is not trivial. However, a true undo, and an undo that meets the users needs are different things entirely. While it's unfair for me to suggest that implementing undo is trivial, it's also unfair to assume that implementing undo has to be difficult.

    I think we have common ground, here. If it's reasonable to put in undo (pragmatically speaking, in terms of money, time, technology, etc.) then I agree the user is better off having it than not.
