New .NET Logos, just in time for PDC

Here is the rationale for the updated logo from Microsoft:

We needed a logo that was in sync with the key values that we want .NET to stand for: consistency, robustness and great user experiences. We also wanted a logo that conformed to the design principles that are driving Microsoft’s brand identity evolution and is reflected in newer brands such as Silverlight, Surface and more.  Finally, we needed a logo that is more strongly aligned with the portfolio of brands that .NET is most strongly aligned with: Silverlight, Visual Studio and our server products.
