Drop-down list versus combo box

from wikipedia:

A combo box is a user interface control GUI element. It is a combination of a drop-down list or list box and a single-line textbox, allowing the user either to type a value directly into the control or choose from the list of existing options. An example of this use is the address bar of graphical web browsers.

But:

The term "combo box" is sometimes used to mean the same thing as "drop-down list," owing to the variability of terms. This usage is likely the result of Visual Basic, and later the Visual Studio suite using the term "combo box" for both types of control.

Uau, this is crazy! When Microsoft consolidated input text and textarea on ASP:TextBox, this was a good thing. Merging DropDownList and ComboBox was also a good thing if DropDownList was the choosen naming...

So I am with those who believe:

This usage is sometimes made more precise as "non-editable combo box" (or something similar). Nevertheless, there are those who consider this usage incorrect, and apply the term "combo box" only to controls that allow edits.
