Design and features

Design and features The Surface tablet line set out its basic design rules with the very first generation of products and has largely stuck to its guns since. What we've seen, instead of wholesale reimagining, is a steady march of improvements to the display and chassis, helping the product feel just a bit more premium with every generation. The earliest Surface Pro models were 13mm thick, while last year's Surface Pro 3 shaved that down to 9.1mm. This year, we're down to 8.4mm, despite increasing the size of the screen. Both the Surface Pro 3 and Surface Pro 4 are 1.7 pounds (771 grams) by themselves, or 2.5 pounds (1.13 kg) with their keyboard cover and stylus pens attached.
