The Road Warrior’s Choice. A 13-inch Laptop is the perfect size for a plane tray table or a cramped coffee shop, but you’ve got to be careful. Some of these are so small the keyboards feel like they’re made for ants. I’m looking for the ones that manage to cram a proper typing experience and decent cooling into a tiny footprint. I’ve checked the screen ratios and the thermal performance to make sure you aren’t sacrificing too much for the sake of a small bag.
