> why would we call anything be anything else but its real name ?

Exactly. There's no point in using the name "Odyssey" for a browser clearly named "Origyn Web Browser". If you were more referring to the use of abbreviations, I think the primary motivation is language economy. I don't see anything bad in using abbreviations, especially if it doesn't cause any more ambiguity than using the "real name" would.

Exactly. OWB up to v1.13 will always be "Origyn Web Browser", no matter how later versions are named.
