so, purchased this today and installed it on another vm to see if there were    
   any differences.  i am not sure, but it seems like the professional version   
   has    
   arca's snap graphics drivers (looks like they bought the rights to that from    
   scitech from what i can tell).   
       
   i do miss the applications store that ecs has, though.  might have to download    
   openchat/2 from there in my ecs machine and install it on my arca 5 vms :)
