My review is based on my own experience on this product.
This laptop provides a 4GB RAM which provides fast installation of applications both by reliably and satisfactorily. It provides fast rebook options since the operating system is Windows 8.1 pro which is a latest version of Microsoft.
The intel HD graphics provides high video resolution which enables a support for many quality application and provides better experience for movies
The surround speaker provides a monster effect which enlightens the quality of the sound system in the product and enables to user to experience a home theatre effect.
the core i3 5th gen is not a lagging processor but also serves at its best at the processing speed for the user interface
A slim design with enough ports and a good keyboard encourages the designing of the product
A trackpad behind the pack is a major drawback of this product and I honestly recommend HP Probook 440 as a servicing utility and commercial traveller
