The latest HP Mobile Messenger is not only sold by HP as Pre-order, it is already on sale on plenty of computer hardware shops at $1,199 SGD ($725 USD). It comes with a Leather Case and Singapore GPS Nav Map.

zenkinz has already got his package and posted a first preview
received the package from my brother-in-law yesterday, did not have the time to try out the phone yet.
but first impression is that the phone is not much heavier than my O2 mini. it's definitely bigger, but much more handier than XDA IIi or HP6365. So I say it's not the best in terms of size, but still good enough at the moment.
in terms of the software support, quite disappointed that there's no map provided nor GPS control panel. There's a GPS quick connect utility, and understand that this will help to ensure faster location-fix than typical GPS receiver, as it downloads the known-location (i.e. Satellite) position during the fix process, instead of downloading directly from the Satellite (which will take minutes).
in terms of camera resolution, surprising find that it's better than O2 mini that I have. I have taken two photos using mini and Hw6515, and you can see the difference. Video taken at night for the Hw6515 is also much better than O2 mini. This definitely wins hand down for Hw6515, vis-a-vis O2 mini and HP 6365
Battery consumption, looks reasonable. After 4-5 hours of playing around, the battery juice drops to 71%. But will continue to monitor.
The qwerty keyboard is useful for sms and situation where you can only rely one hand to message/operate. Compare with other Pocket PC phones that has qwerty keyboards, HP HW6515 would had an edge over the rest due to the size of the device.
