so make two.
poll one says:
IF YOU HAD TO PICK ONE, NOT BOTH, WHICH WOULD YOU KEEP:
( A )
( B )
then:
IF YOU COULD KEEP ONE or BOTH ... WHICH WOULD YOU CHOOSE TO KEEP?
( A ) 
( B )
( C )  BOTH
seems simple.
I SUSPECT:  You'd see most people would choose to keep both, and then you'd also see which
people prefer, if they HAD to make a choice.  Both useful information -- without forcing people
to make a choice based on other assumptions -- like free vs not, community actually coming
together vs another split, support vs not, etc.
I don't have a preference between qtopia and opie -- I like opie because it is free/open -- but now
I'm told that qt is free, what about qtopia?  Anyway, enough of my psycho-babble.
