In a design of the Yoyo concept phone, ModeLabs staff was inspired by the traditional toy. Born from a hybrid energy idea, this concept device powers itself using the solar and kinetic energy. Furthermore, the Yoyo concept uses photovoltaic cells, pendulum with circular movement and the retractable headphones that trigger pendulum motion. Alphanumeric keypad is placed around the handset, and the device have the sensitive keys.
I love the idea. Just imagine charging your phone by playing with it.

Dusan has been using smartphones since their introduction and is now following the latest trends in the industry. The "convergence" is what he's most excited about, and writing about it is the next logical thing to do. He thinks that using a smartphone is what everyone who cares about their time should do.
In addition to his interests in mobile phones, Dusan also loves to experiment with the latest web and mobile 2.0 services. The idea of accessing and managing your information from any device no matter where you are simply amazes him. Whether it's an online to-do list, note taking service or a video sharing social network, he's there to try it out. He admits though, he's still searching for the ultimate web-based organizational tool, which "sings" perfectly with the mobile PIM application.
Dusan used to run SymbianWatch.com which later became part of IntoMobile. He lives in Serbia, South-East Europe, from where he edits the site on a daily basis.
