使用办公设备时，你经常会注意到用户的反馈：而其中只有很少一部分问题可以改善。对于东芝的Tecra Z40 A-147来说，我们认为需要它的输入设备需要一些改进。它的键盘可以有更好的反馈，而点击触控板也不太适合办公用途，尽管你可以使用指点杆的按键来配合触控板。

当你打开脆弱的屏幕上盖时会对它一开始给你的高质量印象有些怀疑。如果你用一点劲，屏幕上盖甚至会扭曲。它的扬声器表现平庸，但对于办公用途来说也无可厚非。较大的色差、低对比度和高黑值让它的屏幕很难被称为一个亮点。

除此之外，Tecra Z40 A-147有很多优势：超轻超薄的机身、丰富的接口都是同类产品中的典范。它的性能表现也不错，同样WLAN和WWAN的信号强度也不错。实用的安全功能，安静的风扇和低发热量也是它的长处。

东芝Tecra Z40 A-147对于需要高质量、高性能、长电池续航的办公笔记本电脑的用户来说是一个不错的选择。如果你对屏幕的要求不高，也不需要长时间用键盘打字的话，它的劣势就很少了。不过，这款笔记本电脑由于我们提到的一些缺点只得到了银牌。
