MSDN Virtual Labs are an amazing tool that's available to anyone for FREE and provide a no-impact environment for learning and experimentation. I highly recommend these resources!

As MSDN virtual labs, developers can get started with VS 2008 in a minute and start exploring the new features. The new labs focus on the language enhancements with C# 3.0 and Visual Basic 9, as well new capabilities in developing web applications.
