As a past Symbian developer, I must say this makes me very happy-
"Nokia to bring Microsoft Silverlight powered experiences to millions of mobile users"
Developing C++ for the Symbian OS (targeting Nokia phones) was a tedious and frustrating experience- forget rapid application development, proper debugging, STL or all the other goodies you learn love and need when developing any application.
After a train-the-trainer SilverLight course in Istanbul and many nights of silverLight development, I truly think that it is a great dev technology and will bring much joy to the world of mobile development.
