Pros
Cons
Inspiron 15 7558从它注重显示性能、内存容量的前代产品设计转而注重全能性和创新。部分采用金属材质的机身在同类产品中仍然十分值得称道(尽管不是特别坚固),舒适的手感和外观特点更像是ZenBook而非Inspiron。传统的输入设备品质优秀;键盘很顺手,也相对安静,触控板尽管采用了一体式按键,由于尺寸较大表面材质舒适也十分易于使用。它的屏幕略微欠缺校准而影响了色彩准确度,同时亮度较低,不过它至少是IPS全高清面板,甚至是最低售价的型号(550美元)也搭配了同样的屏幕。我们的测试机有幸配备了256 GB固态硬盘,让这台售价900美元(约5703人民币)的笔记本电脑配置更加合理。
它的其他特性相比就比较平淡无奇了。性能的表现优劣并存,尽管搭配了强劲的双核处理器,但缺少前代Inspiron 7000产品所具备的独立显卡。系统内存也是如此;虽然从低端型号到高价型号容量翻了一倍(4 GB到8 GB),但都是单通道内存,因为它只有一个内存槽。机身的温度在几个位置会变得很高(不过没有过热降频的问题)。
那这一切又是为了什么呢?更长的续航时间?看起来不像——7558缩小了电池的容量(相比我们测试过搭配独立显卡的7548)以降低整机重量,这让它的电池续航时间相比更强劲的前代产品仅有略微的提高。新的变形设计又如何呢?尽管这是戴尔推广这款产品的核心功能,实际上它只能算是它功能中的一个脚注,因为它的尺寸过于臃肿,很难真正作为平板电脑使用,模式转换也不是非常方便。因此7558在从7548的改变中并没有获得很多的加强,而舍弃了很多,它的设计理念似乎有些走上了弯路。
考虑到Ispiron 15 7558的笨重变形本设计,以及除了节省成本之外的相应牺牲,似乎它的前代产品Inspiron 15 7548反而更加值得推荐。
我们的测试机型建议零售价为900美元(约5703人民币),而搭配Core i7处理器,16 GB双通道内存和AMD Radeon R7 M270显卡的7548相比仅高50美元(不过它没有搭配固态硬盘,而是更慢的1 TB 5400转机械硬盘,不过用户可以自行升级)。因此,尽管它也有一些优势,我们建议用户在选购之前也考虑一下市场上的其他产品。
