Still the ultimate travel companion? There was no shortage of question marks when Microsoft announced plans to launch its own line of Surface PCs, but credit where it's due, in the space of five years, Surface has become a benchmark for others in the industry.

Surface Laptop is widely regarded as one of the best laptops on the market, Surface Studio managed to rekindle our interest in the all-in-one desktop, Surface Book is arguably my personal favourite, and for maximum versatility the Surface Pro still holds plenty of appeal.
