This poor student stuff doesn't fly anyway. You are only going to need something as powerful as Office or Visual Studio when you start doing a degree, and that's covered by a Microsoft Campus agreement. I can get a free upgrade to Vista when it is released, and the new Office when that's released, as well as Visual Studio 2005, and I can keep these installed until I finish my degree. When I'm done with my degree, I won't need them any more, so it's not a problem.
Not being able to afford software doesn't give you a license to pirate the stuff. And a for people complaining about the price of Office, I seriously doubt you use 10% of what it gives you, and can get by fine on Microsoft Works, which is about £50.
And looking at Windows, it's not that expensive. The most costly version of the desktop version is XP Professional Retail. It costs £230, and has been out since 2001. In that time, 5 versions of Mac OS have been released (10.0, 10.1, 10.2, 10.3, 10.4), which each cost £89. Buying each of these would have cost you £445.
