Figure 1-2. OS X's VPN login dialog
The dialogs in Figures 1-1 and 1-2 are very similar. They have an icon, a description, two labeled text
fields, and two buttons. The similarity between these two dialogs is not an accident—it is a matter of
meeting users' expectations. Over time, enough applications laid out their login dialogs in a way similar
to these examples that users would simply be confused by a login dialog that deviated too far from this
standard. Consider the hyperbolically bad example in Figure 1-3.
