The Mobile World Congress 2009 is winding down and a lot of cool products have emerged from it. Both Samsung and LG showed solar-powered phones. A solar panel on the back side of the phone can provide enough power for a 3 minute call after 10 minutes in the sun. The Dick Tracy watch came closer to reality with watches like the LG GD910 that features a touchscreen and high speed wireless connectivity for use as a watch phone. Pico projectors are getting better all the time with the latest batch making use of TI's DLP Pico chip set that will be powering new projectors and even projector phones due out later this year. Reporters noted a conspicuous absence of Android phones at the show however promises were made of new Android phones from Samsung, HTC, Acer, and others. I guess mobile is less about phones these days.
