As part of this launch, SQL Server 2005 Express Edition is now generally available to the public; here are some direct links to help you explore the Express Edtions:

Also launched today is Visual Studio 2005. SQL Server and Visual Studio are integrated as never before and that integration goes all the way through to the Express Editions.
