The BlackBerry Application Suite (BAS) is out and it's getting good reviews. BlackBerry Application Suite runs on Windows Mobile 6 devices and provides almost exactly the same experience as RIM's OS. You basically have a BlackBerry within Windows Mobile.
There are a few limitations however.
Blackberry Maps is there but it is not location aware.
It cannot access physical hardware, such as GPS, Bluetooth, though since calls are through WM, you can use a BT headset.
Video play is not supported.
You can install most BB apps, though some may not support VGA resolutions (should be fine on HTC Kaiser, as it is QVGA)
Currently not all WM devices are supported, only HTC Kaiser, HTC Raphael and HTC Niki. Xperia X1 support is coming down the pipe.
App uses 32 Mb (1Mbx32 files) to simulate BB filesystem
