Yup, the iconic iPhone is wildly popular on the Redmond campus. Sometimes they need to hide their precious device, tho.  Key quote from the Wall Street Journal article: “Maybe once a year I’m in a meeting with Steve Ballmer,” said (a Microsoft) employee. “It doesn’t matter who’s calling, I’m not answering my phone.” Not all Softies hang on to their iPhones, though.  More from WSJ:

Some executives have openly renounced their iPhones. Stephen Elop, president of Microsoft’s business division, used Apple products before Mr. Ballmer lured him to Microsoft in early 2008. But at a meeting of Microsoft sales representatives after joining, Mr. Elop placed his personal iPhone into an industrial-strength blender and destroyed it in a reenactment of a popular Internet video, says one witness.
