Sharp 904SH mobile phone
The Sharp 904SH is a cellphone perfect for amateur astronomers. The mobile phone is equipped with a 3D motion sensor ans specialized software called Seiza o Sagaso, which means "let's look for constellation." By pointing the cellphone towards the sky, the sensor and the software will display the stars and constellation that you can see from your location.
The 904Sh also comes with other nifty features that will appeal to geeks everywhere: VGA screen, 3.2 megapixel camera, a face recognition system (that can shut down the phone when it senses it's not the owner who is using the phone), Bluetooth connectivity, mini-SD memory expansion and standby time of 360 hours.
