We have posted the full livestream video of today's Microsoft Surface labs tour, with Panos Panay and other members of the team showing how they create prototypes of products like the Surface Pro 4 tablet and Surface Book laptop.

The livestream was hosted by Microsoft ExpertZone's Ben Rudolph and runs nearly an hour. It is a really fascinating look at the lab and how the Surface engineering team uses a wide variety of machine tools to shape prototype cases, keyboards and more for the Surface lineup of products. Sadly, we didn't get any new product announcements during the tour; indeed, some of the lab was hidden from view so we couldn't see any future devices in the works. However, it's definitely worth some time to watch as we rarely get to see this kind of prototyping in tech products.
