I like to use the fact that you can't actually touch anything as an analogy for my thoughts on free will. Atoms repel each other and so when you place your finger on something, it can never really make contact. Likewise, we can't really decide anything; our decisions are just a product of our brain and environment. But I think it's silly to say we can't touch things or decide things. The repulsion by the atomic forces is what we really mean when we say "touch", and the way our brains respond to the environment is what we mean by "decide". The words still have meaning even though we have a better understanding of the underlying mechanisms behind them. I also like to point out that although we may not have free will, we still are not fully predictable as the universe is fundamentally non-deterministic. It goes over my head, but those with a better understanding of quantum mechanics should check out the Free Will Theorem lectures by John Conway for interesting thoughts on the subject.
