I didn't have the luxury of the trial versions as I sell my Windows Mobile applications. So a grand later I have my Visual Studio 2008 and am trying each system out to get to my WinMo application.
In the end I settled on C# and it's working nicely. The demo version of my app is out and we'll see where we go to next.
Me? Just a grizzled old embedded electronics designer with a boatload of assembler, Pascal, C, Fortran and other programs done and done. The leap to C# is not that hard.
