Students today prefer hybrid laptops compared totraditional laptops. Majority of them are also looking for a laptop with a good processorand high speed functionality. Besides that, they prefer the screen size of a laptop to be13 to 14 inches. Most of the students today are also heavy task users. That is whymajority of them requires a minimum of 8GB RAM when they make their considerationon purchasing a laptop. The graphic of the laptop is also one of the concerns of thestudents on the laptop. They also think that the media capabilities of a laptop areequally important. However, majority of them are willing to spend a total amount ofRM2000 to RM3000 on a laptop.
