theodp writes: The Official Microsoft Blog hopes a letter from a Nevada middle schooler advising Microsoft President Brad Smith to "keep up the good work running that company" will "inspire you like it did us." Penned as part of a math teacher's assignment to write letters to the businesses that they like, Microsoft says the letter prompted Smith to visit the Nevada school to meet 7th-grader Sky Yi in person as part of the company’s effort to draw attention to the importance of math and encourage students and teachers who are passionate about STEM (science, technology, engineering and math) education. In an accompanying video of the surprise meeting, Smith presents Yi with a new Surface Laptop that comes with Windows 10 S, a version of the OS that has been streamlined with schools in mind. "Not bad for a little letter," the Microsoft exec says. Speaking of Microsoft, Nevada, and education, Bing Maps coincidentally shows the school Smith visited is just a 43-minute drive from the software giant's Reno-based Americas Operations Center. According to the Seattle Times, routing sales through the Reno software-licensing office helps Microsoft minimize its tax bills (NV doesn’t tax business income) to the detriment, some say, of Washington State public schools.
