the article listed some absolute numbers ($1m/yr) and I think hinted at option B below, but didn't seem to explicitly indicate this as;
a.) simply a change from an existing laptop based 1-1 to tablet 1-1
b.) a new cost tacked on top of the budget
c.) cost shifted from other budget areas (no longer buying textbooks)
is there a link to Paul's research?
