I am using Hp laptop for past three years and I bought this for my project purpose. Mine is windows 8.1 operating system its quite good and its user friendly.1TB HDD so I think storage space is more than enough and 4GB RAM, intel core i5 processor wifi is there and good audio and video, power dvd is there. Its worth product and also they providing good customer services. Very easy to handle and you have store to download apps and you cam but there is not much clarity
