Recursive acronym alert

What, I ask, is the point of including an acronym within itself? This is not a new question - GNU means "GNU's Not Unix", after all - but now Symbian's at it. PIPS, we are told, means "PIPS Is POSIX on Symbian".

(The story, by the way, concerns the introduction of POSIX libraries on Symbian OS, which will "significantly reduce the effort required to migrate existing desktop and server components, and mobile applications from other platforms". There you go.)

Anyway, is that just to make people's heads spin Linda Blair-style, or does it betray a lack of imagination?

More recursive acronym fun here.
