Let's carry this discussion one step farther, because I think the can of worms Bluff, Pete, Grifter, and I have opened is a sort of interesting one:

Preflop, you have three choices, fold, limp, raise.
The reasons you might do them as I can think them up right now are:

Fold
Lousy hand
Better hand with a large previous raise
Chip conservation mode with a less than nuts hand
Chip conservation mode on the bubble (here is the possible fold of AA)

Limp
Drawing hand, need to see cheap flop
Slow playing a big hand
No balls, should be in next category

Raise
Value bet to get more $ in pot
Steal
Information, need to find out how big opponents hand is (are)

Others? I know I can't have them all thought up in 5 minutes.
