traditional laptops. Majority of them are also looking for a laptop with a good processor
and high speed functionality. Besides that, they prefer the screen size of a laptop to be
13 to 14 inches. Most of the students today are also heavy task users. That is why
majority of them requires a minimum of 8GB RAM when they make their consideration
on purchasing a laptop. The graphic of the laptop is also one of the concerns of the
students on the laptop. They also think that the media capabilities of a laptop are
equally important. However, majority of them are willing to spend a total amount of
RM2000 to RM3000 on a laptop. Nonetheless, they are also very concerned about the
warrantee that comes along with the laptop. Based on the information gathered,
Taylor‟s University can focus on the aspects to design a laptop that is suitable for the
students today.
