The cheaper car is more like the MacBook; the bicycle is more like the iPod touch. The iPad is more like the flintstonemobile. See my motorcycle analogy from several posts ago.
According to that analogy, I would think the iPad is a motorcycle or moped, which might not be for everyone, but some people do find them useful or prefer them for whatever reason over a car or a bicycle.
Being an activist is an important part of voting. If nobody knows what your preferred candidate stands for, everybody will vote the other way, thus detracting from your cause.
If a candidate doesn't believe in himself or doesn't have enough support to get himself noticed without *my* help, why should I bother? Sorry, but I'm not interested in changing the world, I don't have "causes." *shrug*
