我们将本篇评测在这里分为两个方面来作总结。首先，我们需要列出对这款270欧元（约363美元）的设备可以期待些什么。联想的B50-30作为一款定位于办公用途的笔记本电脑需要在这些方面有突出的表现。对输入设备的需求它可以满足。遗憾的是，它们存在一些缺点。尽管键盘提供了不错的键程，它在一些部分的设计让快速打字变得很困难。它的触控板有一些太小了，不过响应速度很快，它的按键是最大的问题，因为不同的硬度和边框的干扰让鼠标点击操作变得很不方便。它的屏幕从售价的角度考虑是可以接受的，只是对比度如果再高些就好了。最主要的问题之一是它在办公和上网应用中的性能表现。由于较小的工作内存和薄弱的赛扬处理器，在这方面它的竞争者得到的分数更高。联想预装的大量不必要的第三方软件也拖低了系统的速度。这款联想笔记本的优势在于纤薄的机身设计和方便携带的重量。需要更高性能的用户，可以在这个价格找到其他更好的产品，或者等待即将发布的采用Intel Pentium N3520处理器和更大内存的B50笔记本型号。
