The WSJ profiled iPhone usage among employees of Apple’s rival Microsoft, noting that approximately 10,000 Microsoft employees, representing about 10% of the company, were accessing their work e-mail accounts via iPhone last year.

Some Microsoft workers take pains to hide their iPhones. While rank-and-file workers tend to use the iPhone openly around peers, some conceal them within sight of more senior executives. One Microsoft worker said he knows several colleagues who try to disguise their iPhones with cases that make them look more like generic handsets.

“Maybe once a year I’m in a meeting with Steve Ballmer,” said this employee. “It doesn’t matter who’s calling, I’m not answering my phone.”

Interesting ehh?
