HTC made a few Treo devices in the past, like the Treo 650, but Inventec has been the primary ODM for most of these newest devices. I saw the HTC Task Manager on the Treo Pro, wondered about the new flush display like that seen on the Touch Diamond, and also noticed that the bottom soft keys have a touchable area that is quite large to make it easier to activate the soft keys and wondered if HTC made this new device. Chris Leckness at Mobility Site found a DigiTimes report that HTC is indeed the ODM for the Palm Treo Pro.
I think this is great news for the Treo Pro buyer because HTC is a proven player in the touch screen Windows Mobile market. Another thing is that the excellent resources at XDA Developers may be able to support customizations of the device for those who like to tweak things. HTC is focusing more on branding their own line of devices, but still is manufacturing others like the Sony Ericsson EXPERIA X1 as well.
