Our Diamonds is just the same (same speed & 288mb) except no keyboard, flashlight or SD card and 1/2 the flash size, when the Diamond is obsolete so will be the TP. IMHO
I have 2 Diamonds and 2 Touch Pro (1 is broken screen) and I always use my Diamonds, don't like the size of TP for just adding a keyboard really, when have you used the flashlight on the TP? I *RARELY* used it. I think once, and it was not for photo shooting, it was for light!
