It is kind of hard to dynamically create objects whos type is determined at 
run time without them.

For example I wrote a data collection application that uses an abstract 
"scanner" type for data collection.  When the system initializes an instance 
of a class derived from scanner is created and passed to the data collection 
task.  The type of scanner created is selected by a user parameter.

It's kind of hard to do this without access types.  So, while I agree that 
access types are needed for a lot fewer cases in Ada than other languages, I 
disagree with the statement that a high percentage of applications don't 
need them.
