This specific model was manufactured by HTC and felt great in my hand. It was solid and was actually quite light. The OS seemed very snappy in switching applications and running applications. The web browser launched with a bit of fade-in too. Apps like the Calendar had the look and feel of Google Calendar and as a consumer of Google products this device appeals to me. We didn't see any lock ups or other bugs on this device either. It definitely had an HTC feel to it with the button placement and keyboard design, but was also thinner than I though it would be.
