For me, Apple have the best mouse in the world (just usage for designs).

First, it's the one button click on the top. The reason of one button design is for left-handed and right-handed. So, this one button concept can be universally can be used for both hands preference users.

Second, the 360 degree scroll. Simple, it's because it's 360 degree instead those normal mouse. Small ball that keeps the design look steady and nice.

Thrid, the scroll middle button. Default this button is for the dashboard show up. One click to show up the dashboard it's actually a fast access to our favourite widgets, so this is also a good concept of it.

Fourth, the mouse squeeze button on the both side of the mouse. Default this button is to expose all of the windows while you're doing heavy tasks. This feature it's actually good for those who are doing complicated works with a lot windows and applications open. With expose, you can see all of the windows in the desktop and switching it with just 2 actions. Pretty fast and pretty cool.

Finally, where's the right click button? It's actually a touch sensitive button located at the right side of the scrool button. Right-clicking in Mac are a seldom use function, that's why it's located there.

So, the mouse design looks simple from the top. If you count how many buttons, eventually you will get 4 buttons on an Apple mouse. Intellegent Apple? Yes!

RM300 for that wireless mouse. If you use PC, you can't have multiple Bluetooth connections. If you use the Apple ones, you can have both keyboard and mouse wirelessly Bluetooth and you can even have multiple Bluetooth connection with it. This is an advantage on the Mac.

Think again.
