I just found this ...

Who may purchase and use Education Editions?
Anyone using the product for home or educational use. NO STUDENT ID IS REQUIRED. Full or part-time students enrolled at Higher Education establishments defined as accredited public or private university or college that grants degrees requiring not less than the equivalent of six (6) months study OR students enrolled at an accredited public or private school providing full-time instruction.

Now does the bold bit mean any regular joe can buy an educational version as long as its only used at home and not comercially ??
