So it begins!

Oh the uselessnesses of the one buttoned mouse! Read Amy! Read!

The Macintosh user interface is designed so that all functions are available with a single button mouse. Apple's Human Interface Guidelines still specify that all functions need to be available with a single button mouse. However, X Window System applications, which Mac OS X can also run, were designed with the use of two or even three button mice in mind, causing even simple operations like "cut and paste" to become awkward.

To Battle!

Advocates of multiple-button mice argue that support for a single-button mouse often leads to clumsy workarounds in interfaces where a given object may have more than one appropriate action. Several common workarounds exist, and even some widely-used Macintosh applications that otherwise conform to the Apple Human Interface Guidelines occasionally require the use of one of them.

One such workaround involves the press-and-hold technique. In a press-and-hold, the user presses and holds the single button. After a certain period, software perceives the button press not as a single click but as a separate action. This has two drawbacks: first, a slow user may press-and-hold inadvertently. Second, the user must wait while the software detects that the click is actually a press-and-hold, otherwise their press might be interpreted as a single click. Furthermore, the remedies for these two drawbacks conflict with each other: the longer the lag time, the more the user must wait; and the shorter the lag time, the more likely it is that some user will accidentally press-and-hold when meaning to click.


Take that evil clicking spawn!

Alternatively, the user needs to hold down a key on the keyboard while pressing the button (Macintosh computers use the ctrl key). This has the disadvantage that it requires that both the user's hands be engaged. It also requires that the user perform two actions on completely separate devices in concert; that is, pressing a key on the keyboard while pressing a button on the mouse. This can be a very daunting task for a disabled user. Studies have found all of the above workarounds less usable than additional mouse buttons for experienced users.

Oh yes! Oh yes! Take that fiend!

Ok. First I do not use any window programs. Second, I am only using the computer to blog and for the non-profit. I have no use for the left click. Third, I am not handicapped. I can press the CTRL key and use the mouse if need be. I am that skilled. Fourth, all double click mice are ugly. You can't find me a cooler looking mouse than my white Mac mouse! If Apple ever makes a double click mouse, I might consider keeping it in a drawer. But for now, LIVE ON ONE CLICKERS!!!

I'm not taking sides, but last summer we gave away a computer to Amy's Dad. We had both a double click and the white single click to give as an accessary. I decided to give them the single click becuase I figured that you could do more with a double click. I put everything in a box for them to load into their car. Amy freaked out! She was like, "what are you kidding? This mouse is too cool to give away. Give'm the double click." Ha ha ha! I honestly don't care. Although I do need a double click for some games that I play. You guys are both insane!
