In review: Toshiba Tecra Z50 A-12K. Review sample courtesy of Toshiba Germany.

东芝的Tecra Z50 A-12K相比较小的Tecra Z40 A-147给人更完整的感觉。首先，它提供了更高质量、有更广可视角、更高分辨率、色彩还原更准确的屏幕。其次，键盘使用起来更舒适，尽管按键反馈仍然难以满足需要经常打字的用户。

它在散热、噪音控制和能耗控制上的表现都堪称典范，在这里我们无须赘述。只是它的扬声器声音如果更大一点就会锦上添花，不过无论如何它已经完全满足了办公笔记本电脑用户的需求。

可点击触控板的设计显得有些多余，且电池无法直接更换也是一个小缺点。不过，消费者可以得到相对更轻更薄的高质量机身。除此之外，它的外观设计十分出色，整体也很坚固。丰富的接口和稳定的无线信号同样让人满意。

给Tecra Z50 A-12K的无限期合同应该在很多企业都会是个肯定的答复。希望支付它较昂贵的价格来获得一流笔记本电脑的个人用户同样可以毫不犹豫地选择它。
