I just moved from the HTC Desire Z from bell to the HTC Desire HD with telus and there are some small things about the new phone that I am slightly dissapointed with.
1.Where is the dedicated camera button?

Next to impossible to take a self portrait/picture with someone else if you cannot see the touch screen to take a picture. I've paid for an app, Camera Advance, so I could assign my volume rocker as the shutter button.
2. The volume rocker and screen buttons are too flush with the frame of the phone. With a skin on, it's very difficult to depress the volume rocker
Other than that... I'm very happy with it. I wouldnt buy a non android phone, and HTC has not let me down so far.
