Lenovo uses a completely new chassis for the 14th generation of the ThinkPad X1 Carbon. Our IPS model tips the scale at 1.14 kg, while the OLED model is actually lighter than 1 kg. The stability is very good on both versions, but the OLED model feels a bit stiffer, which also results in a slightly better typing experience. Maintenance options (access to internals is very easy) are limited to the M.2-2280 SSD as well as an optional WWAN module (4G or 5G, our unit is WWAN ready with pre-installed antennas). Lenovo uses a modern Wi-Fi 7 module from Intel and the transfer rates in combination with a corresponding Wi-Fi 7 router are excellent at more than 3-4 Gbps.
