For those who may be interested, Microsoft makes available steeply discounted copies of Windows and MS Office for students. $59.95 for Office Ultimate version, $29.99 for a Windows 7 Professional upgrade. Both of these are significantly less than retail or the UW DoIT Techstore.
All you need is to be an enrolled student and have a valid .edu e-mail address.
Also, not to leave Mac users out, DoIT also sells Mac OS X 10.6 (Snow Leopard).
