Re: PythonCE on Smartphone (WM6)

Hi Christopher,

Thank you for your answer, I guess I need to find a port of wxWidgets
/ wxPython or some kind that targets the mobile platform better, or
instead use the Embedded Visual Studio with .NET. I love Python so I
hope there is a better alternative for the smartphone.

Regards,
- Jorgen
