It's very easy to cripple your chips this way.  One slip and the whole side
is bent, or, if not that, then it flips over and nails you in the thumb
(or worse: under the fingernail!!)

You will also find that if you use the method as described above
(by Dr. Robins) that the chips are less likely to come loose.  When a computer
heats up and has tension on them from not being bent, they tend to work
themselves free of the socket (kinda like stored energy in a spring).  Working
at a computer store I found that in some cases a computer could be fixed by
pushing down on all of the chips, thereby re-seating ones that worked
themselves loose.

		Ahhhh, computers: Gotta love 'em!
