The subconscious presents you with choices-it is up to your awareness to decide which choice to make.
Here's the thing. I agree with you pretty much, so that's why this discussion can be a little confusing. We still make decisions. What else could we do? The subtle difference is that I think the choices we make are done in a natural cause an effect way rather than a truly free will based way.
For instance, you can spend 10 minutes deciding between two things, such as raising your left hand or your right hand, but in the end you will decide on one of them. Can you account for why you chose the one you did? You might say, "I am right handed, so I wanted to do something different by raising my left hand". That sounds like a free choice, but where did this idea about "doing something different" come from? Can you account for it's source? Or did that "desire' to be different come from the dark at the last second?
You see, we think our choices are free because we make choices based on our desires, but where did our desires come from? Did you engineer your brain? Did you choose your biology, and along with it the things that you are naturally likely to prefer? Did you choose your environment that you were born into, the very environment that shaped and molded your behavior and opinions?
Did you engineer the concept of "doing something different" by raising your left hand instead of your right? Can you account for why you decided to raise the left? Why didn't you decide to raise your right hand? There were causes that led you to raise the left hand. Causes for which you couldn't possibly have any control over, just like you have no control over your height, skin color or the rate at which you produce white blood cells. Your brain is part of that same system of uncontrolled causes and effects.
EDIT: Real world example. My wife just realized that she lost the remote, and that thing is GONE. Did she freely choose to lose the remote? Did she freely choose to put it wherever she ended up putting it?
People say, "certain things can interfere with our free will" but if a system is only free some of the time, then its free none of the time. If a system was truly free, there would be no room for unfree. Why is it that we accept our mistakes and other events as being cause an effect based ("I was distracted, therefore free will didn't apply") but other times we say we have free will?
