Lenovo ThinkPad Helix 2

联想最新推出的ThinkPad Helix 2延续了前代产品的平板笔记本整合型设备的理念。这让它难以避免地需要在硬件配置上做出让步,不过归功于新一代的处理器平台,它的整体表现有了很大改观。

节能的Core M-5Y71不仅在散热需求上让人惊喜(它仅需被动散热),同时它优秀的性能也可以满足所有办公和多媒体应用的需要。在功效上的提升对于电池续航来说也是一件好事,它仅凭内置的35Wh电池就可以轻松实现6小时的续航时间。搭配可选的Ultrabook Pro键盘底座它还可以更加持久,不过这会为它增加200欧元的成本(相比我们评测的非专业版键盘),不过相对的你可以得到一块附加电池,指点杆,和可旋转屏幕转轴。

说到这里我们不得不提它最大的问题所在:高昂的售价。我们的测试机型目前售价高达1400欧元,尽管它的部件十分优秀(8GB内存,256GB固态硬盘,LTE模组),性价比仍然不佳。再加上它的机身稳定性和工艺质量很难达到联想声称的“高端”水准,它的售价就让人更难以接受了。不过至少它一如既往的出色ThinkPad键盘可以多少弥补一些缺憾。

最后,我们来看一看它的竞争对手们:潜在的Helix 2消费者可能也会考虑以前提到过的戴尔Venue 11 Pro,和微软Surface Pro 3。戴尔的这款设备在性价比上表现出色,而Surface则或许可以通过做工精良的机身来吸引一些Helix的潜在用户。
