"Here's our building, right here," he declares. The conference room where this demo is going on is named after Bill Gates, so it shouldn't come as a complete shock that we're on Microsoft premises. But this isn't corporate headquarters in Redmond, Washington. Han and I are 200 miles away, across the Oregon border in the Portland suburb of Wilsonville, inside a 4-acre structure flanked by a manufacturer of industrial shredders and a storage facility for boats and RVs. Microsoft hasn't played up the fact that it has a major operation in Wilsonville. Actually, it's been downright stealthy about it. (The roadside signage directing visitors to the main entrance doesn't even mention a company name.) But since March 2014, the building is where the company has been engineering the device Han has been showing me, the Surface Hub.
