The mounts are really for vibration - drives are much more susceptible to vibration than shock. The picture of the Neo5100 shows a 2.5" drive, not a 3.5" one which probably accounts for quite a bit of the price difference over the Neo35.

I'd be interested to see what the skip protection was like when playing a vanilla audio CD in the laptop CD drive they are using though - I suspect it's almost non-existent.
