Thanks.  Good point.

That would surprise me if it works well.   Handwriting recognition 
is an awfully difficult problem without some drastic simplifying 
assumptions and those tend to lead to noise.  Consider how badly 
a lot of OCRing works and that for printed glyphs.  

Costs accrue downstream from input sources if the input has to 
be validated by different parties.  We all know the deal having 
dealt with forms-based systems, datatype validation, rule validation 
and so on.  If the entry device *only* speeds up the physical entry 
of data and doesn't vette, the fabled cost savings are lost and 
costs can even go up.   This is typical problem of field reporting 
systems:  the officer doesn't want to spend more time reentering 
data the system says is bad, and the organization doesn't want to 
bear the costs of downstream data scrubbers.  Turning a $1000 laptop 
PC into a pad and pencil doesn't seem like progress unless that 
pencil is awfully clever.
