我想着给自己办公用的鼠标升级一下，反正不是花自己钱，要买就买好一点的，所以pcworld上的鼠标我从最贵的开始挑，最贵是Logitech MX Air™ Rechargeable Cordless Air Mouse，£99.99。
据说不仅能在台面上用，还能在空气中用，而且鼠标能自我感知姿势（有点像IBM某款laptop）。肯定很好玩，但只有800 dpi，而我的主要目的是找个高dpi的鼠标，所以，只好放弃。
排名第二的就数Logitech MX™ Revolution，£79.98。 Logitech依然把它描述得天花乱坠，但我看出了造型比较精致之外，也没什么特别之处了。1200 dpi，勉强合乎我的要求，既然这么贵，肯定有道理，那就选它啦。
I like the first one, because it also was recommended by the financial times for a mordern gift of Christmas. But you have to think about the negative influence when your boss know it. So a excellent mouse without outstanding price will be a better choice. You are really good at it.
I am using Logitech MX™ Revolution now. Very very good, every aspect! I’m happy with my decision of purchase.
