Have you got a HTC Touch Pro and keen to run Android on it but still want to use Windows Mobile?  There is a solution.

Developer at XDA-Developer has used the Gen. Y Dualboot utility to create a dualboot ROM for Touch Pro that allows you to choose what OS to boot on your Touc Pro:

This is a Touch Pro version of my Gen.Y PX-D ROM for the Diamond. It’s an all-in-one, dual-boot rom with XDANDROID. This ROM features a very light & optimized Gen.Y WM 6.1 core (which is accessible, more about that below) & the latest version of XDANDROID v2.1 (27.01.2010 at the launch of R0). The WM Core has all the basic stuff included (e.g. gps, bluetooth, phone, sms, alarm, camera).

This is an all-in-one ROM, meaning it already has XDANDROID cooked in, which is installed and configured during the first boot.
The second boot, u get the custom Gen.Y DualBOOT* (made by myself), which allows u to boot into windows (to update the android build, testing, etc.) or boot directly into android using haret.

However, this is still a work-in-progress.  But do expect better versions coming up.  If you are excited and want to install this unofficial ROM, get it from XDA.
