The reviewer explores whether a thin and light laptop can replace a high-end desktop PC for gaming and video editing. They discuss the MSI GS70 and its powerful core specs, including a 6 core i7 and GTX 1070 max Q GPU. The laptop's performance is tested through GPU benchmarks and editing 4k video, with impressive results. The reviewer notes some drawbacks, including thermal throttling and loud fans, but overall considers the GS70 a great all-rounder machine that comes close to being an all-in-one solution. The main limitation is battery life, but the reviewer believes that PC technology is constantly innovating and improving.
