What reviewers say

Reviewers praise the durable construction, optional IPS screen and battery endurance, especially with the larger external battery. Both find compromises in the input devices: Laptop Mag criticises the shallower keyboard and palm rest, while Notebookcheck dislikes the integrated TrackPoint buttons. Notebookcheck also finds the IPS screen unsuitable for colour-critical work.
