Skype Video Phone launches

Wonder if this stand-alone video phone works on the internal battery or whether it always needs AC power. If it runs on batteries, it might have applications for radio stations in Africa. An increasing source of income is providing chat services between their listeners and their family and friends abroad. Probably need to wait until the price drops, sorry, tumbles below 75 bucks. I am bit worried about investing in a proprietary system - we've all learned the lessons from the Worldspace radio fiasco.
