[Mithalwen]

Just a little point, maybe nitpicking, but Frodo never "wielded" the ring as such until he claimed it for his own at Mount Doom .. he never wore it with intent to control - although he threatened that he would to Gollum. Unlike Frodo who used it merely to disappear, Boromir would have attempted to use it. I do not know if, even with the One RIng, he had the power in himself to control the Nazgul, whose rings were held by Sauron , and could he have controlled the Uruk swho served Saruman? I suspect his fate would have been similar to Isildur's and he would never have made it back to Minas Tirith.
