Been using the diamond for almost a week now. I guess you've all read about the goodies of the device and yes, it handles perfectly and smooth imho, the touchscreen is fantastic, the VGA screen is the best I've ever seen on any consumer device (for it's size). Also the touchflo 3d compliments the VGA screen as well with outstanding graphical detail and functionality (opinions may differ with some users prevering Spb, but I think that's just a matter of choice and what you're used to).
From the outside you can feel the metal frame (where the words htc innovation are printed) and you can feel that it gives the diamond a quit sturdy and strong feel. The plastic backpanel is painted with a high gloss paint which is a real fingerprint magnet, but I can't say it really bothers me except when you're flashing your phone in bright sunlight. What does bothers me is that the backpanel doesn't securely attaches to the device. It unlocks quit easily and mine makes a annoying squeaky sound when pushed a bit right under the innovation text on the side of the phone.
About the battery life, I can make it through the day on a single charge. Did tweak it a bit using schaps advanced config, enabled a bigger file cache, enabled all power saving features but in all I think I get about 14 hrs with 3G/HSDPA on all the time, checking mail from time to time and about 1 hr of call time. So overall I think that's quit decent.
My main concerns are the speaker/ring volume which I think is to low at max, and a bit to loud when you slide the slider just above vibrate. The hw buttons aren't touch sensitive and sometimes the 2 buttons on the left and right (resp call/home and end call/back button) conflict with the directional buttons in the center of the panel. This could be because the frontplate is a single piece of material. It can be quit annoying when you want to push right, but instead press the end key which brings you back to the homescreen.
Also I think opera is a great improvement compared to ie mobile. You just never want to go back to ie again! But there are still some issues. Some pages (esp. those with multiple frames) aren't displayed properly when you double tap to zoom in. Also it's quit difficult to select links on pages. Even if you select the desired link it sometimes just highlights it but doesn't activate the link.
Furthermore there's the memory issue. As stated before you only have about 113mb RAM available of which mine uses at least 70%. Most apps won't have problems running because there is still about 40mb left, but apps like opera etc do use a lot of memory and other future apps might consume even more. So if you plan on using multiple apps intensively it might be wiser to wait a bit for the Touch Pro. Personally I hope there will be a rom update (from HTC or self cooked) available which allows for more free RAM, if it's only to let the touch run a little smoother.
I don't have time for a complete in dept review, but if you have questions feel free to ask.
