Several Microsoft Surface Pro 3 reviewers said in their reviews that the product was thin. Macworld.co.uk mentioned two years ago “Remarkably thin and light for a machine with laptop guts”. Macworld.co.uk also said “The Surface Pro 3 is thinner and lighter than the previous two versions, despite having a larger 12inch display”. Macworld.co.uk also wrote “Thinnest, lightest Core Intel tablet we've seen”.
One person reckoned that it was lightweight. Macworld.co.uk mentioned in their review of the Microsoft Surface Pro 3 “Screen, very good keyboard cover, useful stylus and handwriting recognition, lightweight”.
