Yes you can get FREE copies of Windows Vista and Office 2007 for UK developers.
...all you have to do is attend the Vista/Office launch event for developers were such leading visionaries in the world of technology like Mike Taulty, Martin Parry, Daniel Moth, Mike Ormond and lesser known ones like me will be presenting.
Microsoft will be giving 1000 copies of Windows Vista Ultimate, and 1000 copies of Office Professional 2007 to developers who take part in thier online launch event.
Only thing is you need to have a UK address for us to ship the product to, and we’ll only ship the product when we have it, which could be some time after January (ie it won’t be immediate). Other fairly standard T&Cs apply.
