Call quality was okay over T-Mobile 3G in San Francisco. Voices sounded good--natural, clear, but a bit distant. Callers on the other end of the line had mostly positive reports. When I made a few calls from a busy street corner, however, they reported that my voice was drowned out by the background noise.

The Dell Venue Pro packs in a lot of great features, such as a solid camera and an excellent display. Make sure to give Windows Phone 7 a test run before purchasing, however; the OS has a few quirks, as well as a few missing features such as copy/paste and Flash support. I'm also not sure about the longevity of Windows Phone 7 as a platform. While Android continues to explode and the iPhone retains its popularity, Windows Phone 7 already seems a bit stagnant. Microsoft's promised update to add copy/paste hasn't happened yet. App developers seem hesitant to jump on the platform, as well. Lastly, it's unfortunate that the Windows Phone 7 devices we've seen don't have 4G or HSPA+ support.
