Just by attending one of the Visual Studio 2005, Sql Server 2005 and Biztalk 2006 Launch events, Microsoft kindly sent me the following free software.

Visual Studio 2005 Professional
SQL Server 2005 Standard
Biztalk 2006

Thats nearly £2,500 for just the first 2. (Biztalk 2006 has not yet been released).
There is also a free exam voucher for one of the new Microsoft Certifications.

Thanks Bill.
