This seems to be a really cool device, as it combines two awesome functions. The built-in DV function provides HD (720p) recording with 8 mega pixels resolution, which should make it easier for you to record and share your special moment with friends and families by projecting immediately wherever you go. The Z20 has two lenses; the front side lens provides projecting function and the lens at the back cover is used for the camcorder.
The Z20 has an internal memory of 2 GB, which can be expanded up to 32 GB with external MicroSD cards. It also works with a variety of external devices such as laptop and external multimedia players via an A/V jack or even iPod, iPhone or HDMI enabled devices through optional accessories. The battery life is only 120 minutes on a full charge.
