Developers will get 70 percent of the revenue from applications sold over Windows Marketplace for Mobile, which Microsoft announced at Mobile World Congress last month. In the first details about the competitor to the successful mobile applications business of Apple, Microsoft also pledged transparency, guidance and support for developers selling through Windows Marketplace for Mobile. Developers will be able to set their own prices or charge nothing at all. Microsoft will charge developers $99 a year to develop apps sold through the store. That fee includes up to five application submissions; each additional app will cost the developer another $99. Student developers can ride free by signing up for another Microsoft program. The company noted that there are already 20,000 Windows Mobile applications available. See this story for more background on Microsoft's latest mobile efforts.

A Yalie has sued US Airways for losing his Xbox 360, according to several reports. Jesse Maiman, 21, of Ohio, wants the maximum allowed by law or $1 million in "non-economic distress" from the airline after the console disappeared from his luggage during a December flight. "That thing was my DVD player," Maiman, a junior film studies major at Yale University, told the Cincinnati Enquirer. A spokeswoman for the airline hadn't heard of the suit, but said the liability limit for lost luggage is a government-set $3,300 per bag. "Further, our publicly available baggage policies specifically exclude liability for electronics checked in luggage," she told the Enquirer in an e-mail. That's why I always take my Xbox 360 as a carry on.
