Pros
+ 时尚的机身和优秀的整体性能
+ 低售价型号也搭配了1080p IPS屏幕
+ 键盘尽管键程较短但反馈出色
+ 大尺寸磨砂表面的触控板十分优秀
+ 高速固态硬盘（我们的测试机型号）
Cons
- 作为变形本尺寸过大，实用性有限
- 无独立显卡选项
- 仅一个内存槽（不支持双通道设置）
- 在负载下机身温度高
- 待机时可以听到电路噪音
- 电池续航相比性能更高的前代产品仅略微提升
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。
