联想推出了一台中规中矩的15寸设备，不过它在任何方面都不算出众。看上去廉价感十足的机身不是很坚固，部件的接缝也不均匀。它可能很难给用户带来自豪感。输入设备方面它也让人十分失望：键盘和触控板都无法让我们满意。尽管键盘的狭小按键可以正常使用，不过它的反馈有些僵硬。质量如此差的键盘在笔记本电脑中十分少见。我们认为它的希捷硬盘表现也十分不佳，在实际使用中它让程序加载时间显得异乎冗长。

联想在散热控制上做得不错。它的硬件可以在正常性能上工作而不会受到温度的影响（Turbo得到了充分利用）。B50可以一直保持清凉，在压力测试中也不会非常吵人。遗憾的是，风扇在长时间待机时也没有自动停止。

B50搭配的Radeon R5并不适合游戏。最新游戏通常只能在低细节设置下运行。尽管TN面板提供了不错的对比度和均匀的亮度分布，它的全高清磨砂屏幕也很难在游戏中完全得到利用。不过，让人遗憾的事它的色彩有些偏蓝。由于本身亮度过低，加之在电池模式下的进一步降低，这块TFT屏幕在户外几乎无法使用。

因此B50几乎没有任何优势，而略低于680欧元（约4911人民币）的售价也不吸引人。有限的游戏性能和较差的工艺品质（机身，输入设备）在这个价位没有什么吸引力。

而基于同样机身的350欧元（约2527人民币）售价机型则会给人不同的感受。因此，我们认为搭配更优秀输入设备、屏幕和显卡的多媒体机型更加值得考虑。

首先值得考虑的是Acer的Aspire V Nitro VN7-571G（Core i5, GTX 850M）和Aspire E5-571G（Core i5, 840M）。后者售价甚至低于600欧元（约4333人民币）。同样还有惠普的Pavilion 17-g054ng（AMD A-Series A10-8700P），它提供了更强的游戏性能（R8 M365DX）。惠普的355 G2（A-Series A8-6410）没有搭配全高清屏幕，不过采用了几乎相同的（低端）显卡，售价仅350欧元（约2527人民币）。
