Well I'm no expert, but I would say comparing to the normal wear out due
to use (seeking, bearing wear out, vibrations, spin up, bumps) the
factor of a controlled unload/load cycle on a plastic ramp is probably
negligible.

BTW: my hitachi notebook drive, which I believe has a similar
load/unload technology has:
> 193 Load_Cycle_Count        0x0032   057   057   000    Old_age   Always       -       258528/258360

And it didn't fail on me yet...
Of course this is just one data point.
