I would disagree. Yes, you do have to have someone on the sideline charting your match, but the stats are live and calculated real-time. If you wanted you could glance at them. With a clipboard, you have to do all the calculations after the match (or at least do the calculations by hand).
Also, software can keep records of every match and compute stats over a bunch of matches, or even against a particular player. That's just a couple of examples.
