Lenovo's flagship business ultrabook keeps a genuinely useful port mix in a sub-kilogram chassis. Two USB-C ports run Thunderbolt 4 at 40 Gb/s and double as the charging inputs, while two full-size USB-A ports at 5 Gb/s handle older peripherals without a dongle. A full HDMI 2.1 port outputs up to 4K at 60Hz, and there's a 3.5mm headset jack. Because both charging and external displays share the two Thunderbolt 4 ports, a Thunderbolt dock is the tidiest way to expand this machine.
