I just got one off eBay and hopefully will soon be getting a 'free' dongle, because for the moment I can only key it up on my 120.  I did just take a sec to look around the keys config, though... what could open apple/command (there's actually no command symbol though) possibly be used for?  Like does Cmd-Q return you to extras...?  [that's not a real hypothesis btw - actually there is quitting with some stuff; so maybe Cmd-Q/W do work]  There's no real saving or opening...  I'm honestly just curious.
