Pros
Cons
戴尔的全新Inspiron 17 7778二合一笔记本电脑显然是一个不寻常的设备。变形本通常注重便携性,因此市场上常见的是尺寸更小更轻薄的设备。不过它的大尺寸并不一定会是个缺点,因为多种使用方式也会为传统的多媒体笔记本带来更多可能性,同时GeForce 940MX也可以让它有一定的游戏性能。它的机身品质完全可以令人满意,而屏幕也毫不逊色。在运行中,它的系统可以保持安静。不错的续航时间也应该可以让带着7778出门的用户十分欣喜。
除了屏幕转轴不够稳定之外,我们也对它的键盘质量略有微词,它应该很难满足打字较多的用户的需要。它的显卡在使用中会有降频现象,不过并不严重。测试编辑还发现它的触控屏幕在手指潮湿的情况下响应不太准确。
整体上,戴尔Inspiron 17 7778是一款多用途、设计时尚而性能全面的巨型变形本,它的缺点较少,而同时提供了丰富的使用模式。
