The Microsoft Surface Pro has undeniably carved out a new segment in the PC space. But what was once a powerful, but heavy, thick, and unwieldly tablet when it was first launched, has become a thin, light, and even more powerful tablet in the following years. It was really the launch of the Surface Pro 3 that finally changed Microsoft's fortunes in the hardware game. This was the first Surface Pro that was able to bring the weight and thickness into check, and the 3:2 aspect ratio screen was a revelation in this product category where 16:9 or 16:10 displays were really all that was offered in the Windows world.

In October 2015, Microsoft launched the refreshed Surface Pro 4 which was a bigger improvement than you would have guessed. The overall dimensions and look of the tablet were similar to the Pro 3, but the display was a big step forward, offering 267 pixels per inch, and outstanding color reproduction. The new keyboard launched with the Surface Pro 4 was really one of the biggest highlights though, offering an edge to edge keyboard with island keys, and a far more useable trackpad as well.
