You may want to look into that claim. I was just at the
site and it says that it is upgradable from what I can
tell. I have Office 2000 STE and it upgraded fine. Just go
to
http://www.microsoft.com/office/editions/prodinfo/students/
tour/benefits.mspx and to the second page. You will find
this statement at the bottom of the page:
Note Office Student and Teacher Edition 2003 requires a
qualified educational user in the household at the time of
purchase. It can be used after graduation by the whole
household of the qualified educational user. It will be
eligible for upgrade to future versions of Office. This
product is intended for non-commercial use only. Learn if
you qualify.
