Uni students to get Windows 7 upgrade for just £30
Windows: Student Offer - Microsoft.com
"We are offering students the opportunity to buy Windows 7 for an amazing discounted price, £30 for either Windows 7 Home Premium or Windows 7 Professional
You can take advantage of this offer from October 1st but you will need to be quick as it is for a limited time only and is only eligible to college and university students with a valid .EDU email address (an email address given by the college or university, for example: Suzanne@leeds.ac.uk
), [and] a PC that is currently running a genuine copy of Windows Vista or Windows XP and can run Windows 7."
Also the same offer in the US, for $30. Typical pricing disparity, but with prices that low it's hard to complain about being shafted over the lack of a real exchange rate.
