Microsoft just wrapped its annual Build conference for 2026. Along with agent-first Windows updates, we got a look at the Surface RTX Spark Dev Box, powered by Nvidia’s new Arm-based RTX Spark chips.
Nvidia CEO Jensen Huang then dialed in to talk about their collaboration on the new Dev Box and Surface Laptop Ultra.
