For what it's worth, I have the drill from the new Milwaukee 28V line. So far, it has been really good. It's not as powerfull as a corded drill (duh), but for sure it has more ass than any cordless that I have owned/used before. I think the real test is coming soon...
How does it work in the winter? How long does the charge last vs. all the 18V, 14.4V, etc. tools available? How do the different battery types line up when subjected to low temperatures? I've read about voltage/discharge ratings for different battery tools, but I don't know of any climate related tests. Anyone...?
