[LOTR] What do people think they can do with the One Ring?

People are always talking about using the Ring's power, Boromir wanted to defend Gondor with it, but it seems that it's really only useful for Sauron.  What do people think the ring is capable of that they'd be able to use it?  Even if Boromir had taken the ring, then what?  He turns invisible and fights orcs?

Turning invisible is the least and most blatant of the rings power. Its real power lies in deluding others on the long term, subtly manipulating them to your will, making them see you as trustworthy and proper leader, friend or ally all while having no idea you are being manipulated. 

Boromir takes the ring and inspires the men of Gondor, Rohan et al to fight their utmost against overwhelming odds and each enemy force they defeat joins them as they see the error of their ways in fighting for someone other than Boromir. As things progress distant powers like those of Harad or the Easterlings voluntarily come to recognize Boromir/Gondor's power and stature and come over willingly.  In the end the only hold outs to the Majesty that is Boromir are those with their own power; Galadriel, Elrond, Sauron.
