I use my battery-powered impact wrench all of the time for lug nuts plus its great for hard to remove bolts (like the pulley bolt on a BMW alternator where new alternator didn't come with a pulley and I definitely needed an impact wrench to remove the bolt to swap the pulley from the old alternator to the new one). You never know when you'll need it, but if you do its often the only tool that can get the job done.
Mine is a Craftsman 19.2v C3 Impact Driver, about $120. Very handy to have around the shop.
