Looking at it from the construction standpoint, a lot of that list looks pretty standard for a high-end cordless impact wrench. A couple of things stand out, though.

The other attention getter is the metal reinforced housing. This has the potential to increase the durability pretty significantly. Tools of this general design shape tend to have the handles break on impact. While the plastic outer housing may still crack, the metal lining gives it a better chance to stay in one piece.
