Got a retail model yesterday and love it. I had a touch HD (which I lost on holiday) and so far its measuring up very well. the screen is obviously smaller and there's no 3.5mm headphone socket, but overall I'd say it feels more like a phone and fits better in my pocket. As far as the production ROM goes there are a few things missing which came along with the HD, these are Worldcard mobile, Jetcetprint and MP3 trim, there may be others but those are the ones I've missed. The stylus isn't magnetic, but the phone still knows when you take it out and put it back in again, in fact the non-magnetic gripping action is actually more secure than the magnetic stylus hold in the HD. Its also nice to have proper clickable buttons instead of the touch sensitive ones on the HD, as they are raised slightly they are easy to locate in the dark and light up when pressed or a call comes in. When the screen is off they don't register as button presses so no accidental calls in your pocket or bag. The flashing indicator LED on the front of the device is much more useful than the one hidden away on the power button of the HD. If you can live with the smaller screen size and lack of 3.5mm headphone socket the diamond 2 is in my opinion a much nicer device. Doesn't look or feel at all retro to me, in fact it feels more Sony than HTC if you understand what I mean.
