Basically the only limitation is your own imagination.
Ditto.
I don't have a Dremel brand but same--same. I have many uses for it and I use it often. It makes quick work of things. GMorrison once wrote something along the line of, it's too easy to make quick mistakes using one of these. Bill is SO right about that. Been there, done that. And I also follow Timmys comment about injuring one's self. I have done that too. Depending on the type of bit you are using a person needs to be very careful with it.
But all that said--I continue to use it and it is a big part of my regiment. From grinding to cutting, it makes quick work. In fact. I just recently cut a piece of brass tubing using a cutoff wheel bit. The other thing I use it for is cutting parts from sprue. I purchased a micro tooth saw bit. The wheel is super thin, and the teeth very sharp. It cuts through plastic like butter, and cleanly. I can get right up to the edge of the piece and most often very little cleanup work is needed. Sometimes, none. But that is a bit that scares me and I have to keep my wits about me because one slip will cut you open faster than a heartbeat.
Probably more than you wanted to know. Good discussion.
