My definition of free will doesn't include computers or toasters. I define free will as not only the ability to choose, but also to be aware of this/to reflect upon this and to make this reflection/awareness part of the decissionmaking proces.

(and to further reflect on that to further influence it, etc.)

It is this dimension of reflection that causes the proces to be unpredictable.

If someone would build a computer with this ability, then i would be the first to admit that this machine would have free will.

At this moment however, computers or toasters don't have this ability as far as i'm aware.
