The drawback is that rarely used memory isn't being swapped out, freeing 
the RAM to be used as performance enhancing cache instead.  Of course, 
8GB is way overkill, but even leaving a humble 1GB swap partition around 
is a good idea.  No matter how much RAM you have, the more available, 
the better.
