While in development, the HTC Surround was nicknamed the HTC Mondrian and was leaked on Windows Phone 7 commercials. 
The Surround was released on November 8, 2010. Initial sales data has been reported yet.
The HTC Surround, like its European cousin, the HTC Mozart, was one of the first phones to use the Windows Phone 7 OS. Its main feature are its slide-out speaker which also reveals a kick stand.
Screen and input
The HTC Surround uses a modest 3.8 inch WVGA LCD touchscreen with a resolution of 480 x 800 pixels. It can produce up to 16 million colors.. The display is designed to be used with a bare finger or multiple fingers at one time for multi-touch sensing.
The Surround has 6 hardware buttons: 3 physical and 3 touch. It has a dedicated power button, camera button, and a volume rocker. The device also has a back button, a home button and a search button. The back button takes the user back to the previous application or screen. The home button brings the user to the home screen. The search button opens up a Bing search screen.
The device contains a GPS chip to show the location of the phone, a Proximity sensor to turn the screen off during phone calls so that the face doesn't accidentally click the screen, a G-sensor, an Ambient light sensor to dim the light in dark rooms and increase the brightness in direct sunlight, and a Digital Compass.
Processor and memory
The surround comes with a 5 megapixel Camera with built in Auto Focus and Flash located on the rear of the phone. The camera can also shoot in 720p HD at 24-frames per second.
As is with most other Windows Phone 7 phones, the HTC Surround doesn't support external memory. The phone comes with 16GB of memory: 8GB internal memory and a 8GB internal MicroSD class 4 card.
Audio and output
Audio is undoubtedly the most important aspect of the HTC Surround. When the phone is slid open, the Dolby powered speakers are shown. Most people are underwhelmed with the speakers stating that "The overall volume of the speakers was enough to fill a small room, but not 'take the party to another level,' as HTC claims on its website."  Engadget writes that "there's a lot of promise here, but unless the phone delivers the extra size and weight simply won't be worth it. Unfortunately, we're here to report... that they're simply not worth it." 
The device runs on AT&T's 3G network. It also offers WiFi as another means on connection to the internet. The phone comes with built-in Bluetooth 2.1 and a MicroUSB slot to plug in a MicroUSB to USB wire which can be used to connect the device to the computer or to the wall charger.
Battery and power
The device is running the Windows Phone 7 OS. Despite the name, the OS is in it's first generation. If no longer resembles its Windows Mobile roots. The device revolves around the tile system. The home screen is filled with square, updating tiles. These tiles can be pinned or removed by simply long pressing the tile.
