Orcas is cool. Linq alone is more than worth using it. If you want to see a great example of WPF application look no further than the NYTimes reader application. When you start using Linq you start thinking how you have managed without it so far. I am fairly productive with Orcas, it has it quirks. But I have come to the realization that I am as productive in VS.NET 2005 with CodeRush and Resharper installed. And I don't think Microsoft is in a hurry - there are a fair bit of innovations moving from Net 2.0 to 3.0/3.5. And compared to Winforms - WPF is fast. Cheers Brat
