Have you looked at the OMB filing time estimates on each form? That's a significant investment of time. I've done it many times and I think everyone should do it at least once so they can verify the software's work in the future, because despite what you think software does make egregious mistakes (data flow related, not math) and miss opportunities due to opaque questioning. But, doing it that way every year is not a practical option for anyone who doesn't already qualify for the free filing options anyway.
