The folks at XDA Developers have created a great port of Android OS 2.0.1 that can run on not only one, but most HTC Windows Mobile based devices. This port has been created by XDAndroid team, and as they claim it, it is so far the best port of Android to WM-based devices.
This port is fast and stable, and has been tested to work great with HTC HD and Touch Pro2. This Android port is also the most beautiful, running on a simple but nice theme with lots of beautiful wallpapers and more.
There are certain known issues with this port, just like with any other. The developers at XDA are aware of most of them, and working to resolve them as we speak.
Visit this thread at XDA Developers for a complete list of known issues and links to download the cab file as well as how to install it.
