This is definitely a real problem for some people - a chess organizer friend of mine recently spent 4-5 hours entering games from a scoresheet into the computer every night. This solution is pretty nice - but it is possible to imagine that such a solution might work directly on horribly written scoresheets, using handwriting recognition + the kind of constraints mentioned by indy7500 - that would be pretty amazing from both a technical, and usefulness, standpoint.
