Microsoft: Surface was developed in an 'underground bunker' at first, we can play the secrecy game too

We commonly associate extreme secrecy around a product design with Apple, but it now looks to be in vogue with all the major technology companies: just days after Samsung revealed the Galaxy S III's secret sauce, Microsoft has explained to TechRadar that it developed its surprise new Surface tablets under a similarly tight watch. A special wing of Microsoft's hardware unit initially worked in an "underground bunker," according to the division's Stevie Bathiche, before moving to a more conventional building with an 'airlock' door -- the company was just that concerned that Bob from Accounts Receivable might spoil the whole thing. As we all know by now, that level of secrecy proved effective almost until the last minute and let Microsoft design to its heart's content; we still don't know if other PC builders were aware. The practice is a sharp break from Microsoft's tendency to telegraph its strategy well in advance, and it emphasizes just how much importance Redmond places on its self-developed Windows 8 hardware.
