I own Acer 4710Z from past 2 years and I must say the hardware quality is not great. I had to change the key pad 3 times as the quality was too bad. Very soon this laptop would encounter flickering monitor problem, that calls for replacement of monitor as well. I think Acer company to should seriously reconsider this and make this laptop more roust. Although on brighter side it can use Win-7 OS which is comparatively faster then Win-8 or 10 variants. This is too bulky design and heavy to carry.
