A questionable rumor has Microsoft's Steve Ballmer making a presentation at Apple's WWDC in roughly two weeks. Global Equities Research analyst Trip Chowdhry believes the Microsoft CEO is penciled in for seven minutes of time at the keynote and would talk about a new version of Visual Studio 2010 that would produce iPad, iPhone and Mac apps. Chowdhry didn't say whether the purported source came from Apple, Microsoft or an in-between party.
