What to expect at Microsoft's Windows, Surface and AI event on October 7

NVIDIA is once again claiming it will redefine PCs with its RTX Spark, the company's first major Arm-powered chip built for massive AI models on Windows laptops and desktops. The Surface Laptop Ultra, which was announced in June, is one of the first devices powered by RTX Spark, and from the brief glimpse we got earlier this year, it appears to be a direct competitor to Apple's powerful MacBook Pro. It sports a 15-inch mini-LED screen with up to 2,000 nits of peak brightness, a massive trackpad and all the ports you want. But we still don't know how much the Surface Laptop Ultra will actually cost, and there's no concrete release date yet. I'd bet the company is saving up those crucial details for next week's event.
