For those who think it looks intrusive, not much to say. I'm guessing more different than anything. I haven't turned it off in a long time but honestly rarely even notice it.
For those who don't like the relative coord default, you can change it in the setting to default to absolute.
I tried it when it first came out and didn't like it because in some circumstances (I don't remember what it was off the top of my head but it was common) the space bar would have to be pressed twice to enter. Since the space bar is my usual enter key in acad, that was a killer. That got fixed so it doesn't bother me now.
