This is a great release… something MSFT should really be proud of and a real enabler for amazing experiences across multiple platforms.

I am just finishing up my first v1 of an SL3 project that we have been building on beta bits and the experience has been great. Its not so hard to be a WPF guy in Silverlight anymore.
