I'm no fan of the right-click disallowance.  I'm 
another who prefers to open pages I want to view 
in a new window rather than having to constantly 
hit the back button, so I tend to find myself 
less inclined to browse sites with that feature. 
And, like you said, it really doesn't stop anyone 
who wants to take an image.  
I must say, I'm glad you brought it up, though.  
I'm glad to know I'm not the only person out 
there who doesn't really like that hassle. ^-^;;
