Microsoft - Surface 2.0 - Tablet - Black - on StandMicrosoft's Surface event in LA was mysterious. In fact, the company didn't share where the announcement was being held until a few hours before it started. It turns out, the entire thing was by design. So how did the Redmond company manage to keep prying Internet eyes from revealing what turned out to be one of the best surprises so far this year? Bank vault-level security, airlock-style doors and an underground bunker with no windows.

Microsoft explained to TechRadar that on its journey to Monday's unveil, the team worked tirelessly on multiple prototypes. "We care about the bigger idea, but also the smallest detail," Microsoft's Stevie Bathiche said. "It takes iteration to make great devices and each time we made one of those revisions [Surface] got better and better."

But just because the Surface devices are, well, above surface now, don't expect its deepest, darkest secrets to be unveiled by janitor Steve who fortuitously stumbles across the company's plans. Stuff like battery life, price, release date and processor speeds are still being closely guarded. From TechRadar's description of the operation: What goes in the Surface building stays in the Surface building.

Getting into the Surface building means going through airlock-style doors; the outer door has to close before you can get through the second door and go inside, so you know there's no-one sneaking in behind you.

The tablet market is fiercely competitive, so you can understand why Microsoft put so much emphasis on keeping the Surface a secret. Monday's announcement is a new step forward for the company, which typically relies on others to handle the hardware aspect. I wonder what other stuff Microsoft has cooking up in its secret labs? A smartphone perhaps?
