Honestly, I'm not sure how useful they are. I guess their real use is to quickly discover new places without engaging in combat. Just quickly run from one end to the other.
I have found a much more interesting use for them.
They can carry you and you can fasttravel without any weight-limit.
So once I got overburdened because I felt in love with all that junk in a Dwemer ruin. I couldn't fast travel (because overburdened) but then I saddled up. Don't ask me how! With 4x maximum weight capacity it probably involves magic. A LOT OF MAGIC. But one the horse, I could fast travel again...
