Pros
Cons
售价129美元的Tab 2 A8是一款值得尊重的平板电脑产品。它的屏幕亮度和电池续航时间均优于平均水平,而在低价市场中它的音响效果也十分出色。遗憾的是,它在其他方面就没有什么突出优势了。1GB内存和800p分辨率的屏幕让我们感觉在2015年对于平板来说还是有些过低了。它相比其他的8寸机型也更沉一些,触控屏幕偶尔会有识别错误的情况。
对希望购买一款8寸平板电脑的用户,相比Tab 2 A8我们更推荐联想Tab S8。Tab S8更轻薄,屏幕更明亮,整体表现优于Tab 2 A8,目前售价169美元。多出的40美元绝对物有所值。
对希望购买一款8寸平板电脑的用户,相比Tab 2 A8我们更推荐联想Tab S8。
