In addition to Windows Phone 7, the HD7 comes preloaded with Netflix, Slacker Radio, and T-Mobile TV, among others. However, not much has changed about the hardware as it shares the same screen, processor, and battery as its predecessor, the HTC HD2.
The HTC HD7 measures 4.8 inches tall by 2.7 inches wide by 0.4 thick and weighs 5.7 ounces, so it's a bit on the bulkier and heavier side. The upside is that you get a spacious 4.3-inch touch screen. We just wish it was slighter sharper and brighter.
