having gideros studio makes gideros more accessible for newcomers. there is no complicated setup process, look how much trouble it takes for people to set up zbs, even though it's almost trivial. also you can reach examples immediately. and it has a menu tailored for multiple device testing etc. gideros specific things.
so i don't see it being obsolete soon but i'm completely for being able to do everything from command line so that from zbs etc. you can theoretically also do everything.
