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 :)
