This is, by now, old news, but if you're an MSDN subscriber, you'll definitely want to go get the RTM (Release To Manufacturer) versions of VS.NET 2005 and SQL Server 2005. If not, but you anticipate running .NET 2.0 applications (which many undoubtedly will), the released 2.0 Framework is now available for download.
This is an exciting time! I can't wait for the launch event. I'm heading to San Francisco for the launch on the 7th. If you're going to be there, drop me a line and let's get together!
