Aah! Just remembered my reason for saying that about the BEN Kenobi thing..

Someone on cracked.com said something like.. Why the hell would Obi Wan change his name to Ben but keep the surname Kenobi, if he were to hide his identity from the EMPIRE.

Hence I said.. BEN was more likely to hide his first names (which have a Jedi like sounding name.. ie: Obi Wan/ Qui Gon/ Ki Adi Mundi etc.. All very Jedi sounding.)

In the prequels,robots were seen as the Villains (trade federation) When I studied Star Wars in film studies (before the prequels were made) There was a whole "Race" /discrimination topic about why the Droids weren't allowed in the Cantina. (The prequels gave reason for this, small minded folk that remembered the trade federation/distrust of droids)

Also, in ROTS, the Jedi were framed by Palpatine and were outcast. So to be a Jedi living on Tattooiine OBI WAN would have found himself not blending in very well, or even being reported to the Empire. (So his tripple-barrelled-JEDI name changed to Old Ben makes sense.)

I also mentioned Chewie and Ben APPEARED to have met prior to the meet at the bar. Well, its 50/50 either way.

Hope that explains what I said earlier a bit better. More to a response to what someone said on Cracked.com.. But more relevant to what RadiOn was saying.
