We have free will. It just isn't what we think it is. If will is not caused by anything, then it is a random event -- hardly the same as personal volition. It will is caused by previous events, then it is determined. Determinism or not-determinism says nothing about what free-will is.
Free will is the ability for a conscious entity to choose (or think it is choosing) a path that is usually useful to itself. Whether it actually chooses anything is not the point -- it thinks it does. The fact that we cannot predict the choice makes the illusion of freedom more complete. One could argue that any response that is 90+% predictable is more of a hard-wired reflex and not really a choice, but even then we "think" we've made it if it involves cognition.
