Lenovo ThinkPad X1 Carbon Gen 11, the classic business ultrabook, with 16GB of soldered RAM and a 512GB SSD. It weighs just over a kilogram, so it disappears into a backpack, and the keyboard is still the best in its class for anyone who types all day. Real-world battery life lands between eight and ten hours of mixed office use, and the fans stay quiet under normal loads. The laptop was a corporate device that I bought at the end of its lease, so it has been serviced regularly and carries no BIOS lock or asset tag restrictions. Cosmetically it is excellent, with only a faint mark near the hinge that photographs worse than it looks. Includes the 65W USB-C charger and a padded sleeve. Located in Queens; I can meet near a subway stop and let you boot it up and check everything first.
