What reviewers say
Reviews praised the large screen, viewing angles and capable everyday performance. Macworld found modest speed gains from the Core 2 Duo model; Ars Technica valued the display but noted limited upgrades and DisplayPort-only input. TechRadar criticised uneven backlighting, the glossy finish and the absence of Blu-ray.
