HP's ProBook range is intended to combine business functionality with elegant design. Originally launched with 15.6in. and 17.3in. widescreen models, the series has since been bulked out with a couple of 13.3in. variants. Here we examine the top-end ProBook 4710s with its massive 17.3in. screen. There are currently twelve variants of the 4710s, with our review sample, the 4710s NX427EA, one of the most expensive at £815 (ex. VAT). The least expensive is just £539 (ex. VAT).
