Probably one of the larger complaints about Windows Mobile is how it's lacking a bit of the shiny. In other words, the user interface could use a little sexing up. In this session from Tech-Ed, Andy Wigley and Andrej Radinger talk a little about what developers can do to spruce things up.
Actually, we're being coy. The name of this video is "Can Windows Mobile UIs Look as Good as the iPhone? Yes, They Can!" And the description:
True, the standard controls in the Visual Studio Toolbox look a bit 'Windows 95-ish', but armed with some fairly simple programming techniques, a little knowledge of how controls get painted on the screen and the skills of a decent graphic artist, Windows Mobile developers can create applications that look great--and enjoy the far superior productivity that developing with the .NET Compact Framework gives you.
Interesting stuff. Give it a look-see here.
