Wow, there is a lot of anecdotal evidence in this thread. Has nobody taken a statistics course? Probability, guys, come on.
It's simple: take the shot, reduce your chances of getting the flu. Also reduces your chances of passing on said flu to other people. Side effects are practically nonexistent, despite fear-mongering to the contrary.
As for H1N1, the shots were given before the mortality rate was figured out, and continued to be given due to media frenzy. Our population density is screaming for a pandemic, and disease control centers have a hair-trigger on their response. The media made the panic worse.
If you don't want to take the shot, it's fine; it's not a big deal. The idea that you are better off having not taken it is absurd.
