The cost of frequency's advancement is relatively high.
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.
