I don't have an impact as of yet, I have 28v milwaukee and they don't make an impact that would be useful for driving screws, might be nice for lug nuts smile
I can see an impact for working in wood but most of my stuff is in steel so I don't see much value

Thats good drill, the cords are widely available and they don't fall out of the drill. I believe the cord fits other Milwaukee stuff also, sawzall for one??
