@igm,
Sorry, not convinced, but still think you're onto something important.
1. I don't know about you but I tend to resist taking decisions untill the last moment. It's not like I enjoy my illusionary free will so much that I look around for decisions to take. And not only me, I think many people shy away from decisions, especially those involving insufficient info, until such a time when it would become detrimental (as you said) to procrastinate any further and we feel the 'urge' to decide one way or the other. So if free will is 'meant' to sugar-coat such difficult decisions, to cure us from our indecision in the face of doubt, it's not doing a very convincing job at it.
However, we sometime happily jump in the unknown. That sort of adventurous behavior is perhaps facilitated by an illusion of free will? Still in my introspective self it's more related to carelessness, to saying 'WTF, I'll try', than to a sense of freedom.
2. Computers (eg games where you fight against the computer) can take decisions in a given time. They don't need conscience or free will or anything like that to do it... In fact they probably go faster for their absence of such complex, heavy systems.
