To counter with an alternative tool comparison: drills and impact drivers look very similar. I'd bet that most of my friends don't really know the difference. But for some situations, an impact driver is an entirely more capable tool.
If you use a drill all day, professionally, you'd be a fool not to take a serious look at an impact driver and see if it makes your life easier.
