Woo-Hoo! If you have an Asus device they are providing free upgrades to Windows Mobile 6 Classic and Professional for the ASUS A639/A626/A686/A696 and ASUS P535/P735:
Asus have also announced the new M530w device. The device is a Windows Mobile 6 standard device with integrated 3G and WiFi (802.11 b/g).
The specification is pretty much standard fare however it does include a neat Business Card Scanner application using the integrated 2.0 Megapixel camera. I haven't laid my hands on one of these devices yet but I wonder if it's the WorldCard Mobile application?
