I am a big fan of mobile applications and recently due to our migration activities
(we now offer migrations from VB6 and WinForms to Silverlight)
have been involved with Silverlight programming.
I have done some mobile application development activities
in J2EE and flash and I am now very happy with Silverlight.
What makes me even happier is that I am a Symbian fan and I can now
start developing applications for my Nokia phone with silverlight.
