 how long does it take to press a PCMCIA button and pop out the CPU
Card?  2 seconds absolute maximum.

 what tools does it require?  none.

 what special precautions are needed?  none that are not the domain of
common sense.

 all the other examples require tools, special handling (you cannot
touch the gold edges or pins), and some considerable amount of time.
in the case of replacing a CPU it takes a lot of time because
depending on the design the heatsink also needs to be replaced, and
the paste renewed.

 so it is _completely_ different, stephane.
