I thought that rubystack was focused to give the users everything they need to start working with rails avoiding environment setup as well. Sorry but I am trying to see the difference but I am not sure if I can. So then the difference is some kind of friendly/more advanced installation interface and an easy way to get started installing less "stuff" than rubystack does?
