戴尔改进了它们的Latitude E55中我们指出的所有不足,在不降低续作质量的前提下解决了这些问题。同时,这款产品还向未来跨出了一大步:在这个数码时代几乎没有人用光驱了。去掉光驱之后,笔记本电脑的机身可以变得更薄。Latitude E5550就是这样,它相比前作看上去更加现代也更加优雅。
它的机身现在也更坚固了,屏幕的色彩更加准确、明亮,它也终于采用了IPS屏幕面板。它的触控板面积更大,而键盘也变得更加简洁,提供了舒适的使用感受。非常低的运行噪音和只在机身有限的一部分区域的升温也都给了我们正面的印象。
不仅只有企业用户可以使用戴尔Latitude E5550。希望为家庭办公用途购买一台笔记本的个人用户也可以考虑这款戴尔的商务笔记本产品。他们将会得到纤薄,相对轻盈且防滑的机身,音效饱满的扬声器也可以帮助这款设备适应多媒体用途。技术宅也会对它方便地维护升级感到非常满意。只有游戏玩家需要看看有没有别的选择,因为它没有配备独立显卡。
整体上,这是一次非常优秀的更新,我们几乎找不出任何问题。当然,用户无法得到金属材质的机身,它也没有第二个音频插口,且电池也无法从外部直接更换。但它的电池续航虽然相比前作较短,相比同类设备仍然更加优秀。不过,这些都不是很严重的缺点,因此我们认为它对于需要一台可靠办公笔记本的用户来说“绝对值得考虑”。
