Samsung W7900 Projector Phone With 5.0 Megapixel Camera

In January Samsung had unveiled the W7900 projector phone. The W7900 can display video on a 50-inch screen courtesy a Texas Instruments DLP Pico chipset in the phone. The W7900 features a 5.0 megapixel camera front-facing camera for video calls and an OS that supports widgets.
The DLP projector has a 480 x 320 resolution and can be controlled from the 3.2-inch 400 x 240 OLED touchscreen. So basically with this phone you can share PowerPoint slides, view images, and watch videos. The phone comes equipped with built-in speakers. The projector projects on any flat smooth surface giving you the opportunity to enjoy a novel multimedia experience. The projector light can also be used as a flashlight. Samsung is promoting the feature as a neat tool for instantaneous media sharing that expands the scope of using the mobile as a tool for business presentations.
The W7900 supports 3G HSDPA up to 7.2Mbps and global roaming (900/1800/1900 MHz).
The W7900 is set to be released in Korea this month followed by a European release where it will be sold as model I7410 but apparently without the projector. As of now no pricing details are available.
