Well they should. If you don't even need to itemize you should just fill out the forms from the IRS. If you can do some simple addition and subtraction it's not difficult. Probably just as fast if not faster than being interviewed by your tax program.
But why? I mean we're in a forum if tech nerds and people are seriously advocating filling out a form and doing calculations manually?
You're missing the feature where your information is carried over year to year and all the forms you get can be automatically parsed. "Doing your taxes" with current software can be as simple as uploading a few PDFs and clicking next a bunch of times.
