How Microsoft built its MacBook Pro competitor

Microsoft tests its Surface devices in a lab on its Redmond campus, where robots simulate real-world use and devices are exposed to radio waves from giant antennas, to ensure they can withstand various types of wear and tear before releasing them to the public. The exact details of the testing process, including the number of button presses and types of scenarios simulated, were not disclosed. The lab is used to test both hardware and software components of the devices, and the goal is to identify and fix any issues that may arise during use.
