HTC Touch Pro 2
The Touch Pro 2 is treated to most of the same upgrades. Its screen stretches to a full 3.6 inches, which is just .2 inches smaller than the monstrous TouchHD. It gets a louder speakerphone system and less-pixely camera than the Diamond2, but retains the larger battery and slide-out QWERTY keyboard that originally distinguished its dad from the Diamond.
Battery life is apparently boosted by 50% on the Diamond2 and "improved" on the Pro2, a change which is more than welcome, as this is one of the areas where the original Diamond/Pro fell down. Other, less immediately interesting new features include "HTC Push Internet", which is essentially pre-loads parts of your favorite webpages, and the inauspiciously-named "Straight Talk", which allows for easy transitions between text or email communications and regular or group phone calls, letting you immediately initiate a conference call with, say, the recipients of an email thread.
