I returned the Moment because of a poorly designed keyboard and a loosening slider. This return happened inside the 30 day window. A loose slider in less than 30 days... very unacceptable build quality. I ended up with the Hero. That was an awesome phone. I have had many HTC phones and they have had very good build quality. I didn't care much for the operating system (WM6), but that wasn't HTC's fault. I have had several Samsung, Sanyo, LG, Palm, Motorola phones. All of those makers suffered from poor build quality. I know the Epic will be stricken with problems and people will be looking to the next phone as the "perfect" phone. The Evo just plain rocks. Also, I would avoid sliders at all cost. They just don't seem durable enough (e.g. Mogul, Moment)
