After our initial caffeine-fueled lap around the Orange County Connection Center, we made the rounds one more time to collect some videos for your scrutiny. One device on our hit-list was the HTC HD7S, AT&T’s third Windows Phone 7 smartphone. If you’re a Windows Phone fan, this one is sure to be up your alley. Its 4.3-inch screen was bright and its build was solid thanks to thick plastic and metal accents. We do feel the design is getting a bit stale, though, given that it has a body that’s very similar to the HD7 on T-Mobile and the EVO 4G on Sprint. It even features the same kickstand, which is good if you want to watch movies and set the device in landscape mode on your desk, but it also adds some bulk. The HD7S would be our top choice of Windows Phone 7 devices on AT&T too, because it has the latest NoDo update that includes copy/paste functionality. Hit the jump to see what the HD7S is all about, and check out our photo gallery as well.
