In Review: Lenovo Tab A8
In Review: Lenovo Tab A8

180美元的建议零售价,对于注重价格的消费者来说联想Tab A8是一个很有吸引力的选择。它的性能足够满足日常应用,电池续航则可以满足一整天的使用。这款平板的设计并不是非常让人心动,不过机身的做工很好,8寸的IPS屏幕则提供了看起来十分明快的色彩和舒适的对比度。当然,三星 Galaxy Tab Pro 8.4Apple iPad Mini Retina几乎在所有方面都优于Tab A8——不过它们都有更高的价码。Google Nexus 7有一块更高分辨率的屏幕和出色的屏幕亮度,不过缺少大多用户需要的microSD卡槽。联想自己的Yoga Tablet 8相对高20美元,提供了超长的电池续航时间——不过它标新立异的设计可能并非所有消费者都会喜欢。
