It keeps at the same level as our rivals' and it will not make notable difference to laptop's performance. Have additional value in the patent technology Hard to improve in a limited time. Thickness and size has great influence on weight. The expense on disk research is low and will boost customer's satisfaction.
4.CONCLUSION Improving goals: A thinner and smaller laptop equipped with a bigger capacity.
