Milti, for almost every product there are good and bad reviews ... you have to see the overall rating. That laptop has a very low end CPU and 1/3rd of the reviewers give it 1 star even though the price is so low and their expectations couldn't be high!! Your old Samsung NP350U5C is MANY times better. It has an i5 CPU which gets an average mark of 3797. That new laptop you bought now gets 865 ... it is more than 4 times slower!!!

The ones I suggested are still slower than your Samsung at about the 2500 average mark ... the bare minimum for an OK experience!
