Marble is a generic mapping app, not all of KDE. At first I thought it was a theme like Plasma is.

But this still goes to show that KDE apps can be made to run on Maemo.

I'd rather have navi than marble, but its a step in the right direction. I'm really glad to see the KDE team playing attention to Maemo and hopefully Meego.
