Free Microsoft Software (including VSTS) for IEEE Computer Society Student Members
I'm a member of IEEE and IEEE Computer Society and recently received requests to renew my subscriptions. I was pleasantly surprised to see that in 2008 student members of IEEE Computer Society can receive free software including Vista, Project, Visio and most interesting for me, Visual Studio Team System.
Both subscriptions come with monthly journals which are pretty technical and provide glimpses into various potential future career paths.
UPDATE: If you're a student in the US, Australia or a few other places you can also get Office Ultimate 2007 for up to 90% off the retail price.
