Anti-shake reliability?

Sorry if this has been addressed, but is there any info regarding
reliability and longevity of "anti-shake" systems? In other words,
looking at "another mechanical thing to go wrong," it seems like it
must be a delicate and complex little system. When and HOW does it
fail? Can it CAUSE problems? Can it be disabled?

Perhaps those who have had experience with these things can shed
some light?

Thanks in advance,

Image stabilisation in cameras is delivered either by optical
stabilisation or by comparing and aligning frame to frame shots.
I'm not aware of any video cam that stabilises the CCD.

That said there's no reason to suppose that the actuators cannot be
made reliable. Whilst typing this I'm listening to the tick-ticking
of the heads in my laptop's hard drive. Incredible number of
movements per second and used over very extended periods of times
and worls a dream.

Minolta says this gizmo moves the CCD, unless I misunderstood
phil's explanation.

But good point about the HD mechanism -- I haven't had one fail yet!
