The 64 GB/1 TB Surface Laptop Ultra suits development and local AI projects that need more shared memory than the entry configuration. Its 15-inch touchscreen and broad port selection make it useful as a mobile workstation, while the 2.0 kg body is a portability tradeoff. The stated battery figures are up-to claims under light, 150-nit test conditions, so plan power for demanding GPU work.
