WRONG. WRONG. WRONG. 
Dynamic linking gives you a level of indirection that allows you very 
easily to update algorithms and such in the OS/Toolbox while not having 
to touch existing apps. 
Look, for example, at QuickTime. QT 2.0 comes out with new improved 
blitters and all QT apps run fast---doen by dynamic linking through 
Component Manager. 
The same thing is true for CFM. One can replace a CFM shared library with 
a new version (for example one that now uses natve PPC code rather than 
68K cade, like the Sound Manager 3.0 to 3.1 transition) and your apps 
again go faster without you touching them.
In the case of SOM-style or Component Manager-style dynamic one also 
now has the ability, as a programmer, to override only a few calls to 
modify the behavior of some entity while inheriting the rest of the 
behavior. Object-orientation, but language netural and built into the OS. 

Please get your facts right in future.
