If you need a laptop that’s not just light, but among the lightest of the light, you’re looking for the 14-inch Acer Swift 5. At just 2.31 pounds, it’s one of those devices that messes with your mind. When I pick it up, I feel like I must be holding a hollow chassis. When I put it in my backpack, I spend the day worrying that I might have left it at home. Sure, there are lighter laptops out there — Asus’ Expertbook B9450, LG’s Gram 13, Acer’s Swift 7, Samsung’s Galaxy Book S, and Dynabook’s Portege X30L-G all weigh a bit less — but some of these models are either significantly more expensive than the Swift 5 or a step down in performance. If you’re looking for a real-deal processor for a mainstream consumer audience, the Swift 5 is about the lightest you can go.
