I object. Leading. Adding in "contenders" skews the poll. For instance: you neatly glossed over all the Apple offerings in those fields, and as Apple holds a larger, and just as rabidly fanatic, user base than OS/2, it clearly doesn't take into consideration the _entire_ industry.
Moreover, different flavors of Unix cannot be lumped into the same category! Linux is a _very_ different beastie than Solaris, and AIX is alien compared to OSF Unix.
So, just set up the categories, and let the participants fill in their own blanks.
