I think the LED is a good idea, and that is what is done on the PocketBook Pro devices. I wanted to point out that some people complained about this feature because it ate up some battery power (probably shortening the time between charges from 30 to 29.5 days). I guess the spinning wheel would produce the same complaint. I find it amusing that it is hard to make an improvement without someone seeing it as a step backwards, no matter how good the idea.
