Could we have a WP section in the forum, please? Many of us have already downloaded the SP7 SDK and have started building and porting our apps to WP7. It would be useful to be able to start discussing topics such as Silverlight, XNA, C#, deployment, etc. Visual Studio is an easy IDE to use, .NET is a powerful dev platform, and you can write code in C#, VB.NET, Python, Ruby, C++, etc -- or just drag and drop UI controls from the toolbox. The coolest thing about Silverlight applications is that they run in the web browser and on the desktop too!
