The power tailgate is a nice feature. It's not that the tailgate is heavy or difficult to close, it's the fact that you don't have to slam it shut. The tailgate was a very bad design on the E53...mine still rattles to this day. The trunk latch has also been replaced three times. I know from this board that it was a common problem. I'm glad BMW finally did something about it. It's too bad that this feature is delayed though...
